Landsat, the Longest-Flying Earth Science Mapping Mission


George & Virginia: Their Vision Is a Profound Legacy

GreenPolicy360 Siterunner Steve Schmidt: Back in the 60s and 70s, my friend George E. Brown was a key force in the U.S. Congress creating a first generation of earth science missions from space, remote imaging it was called. I was fortunate to have become close to George and his work as we each, in shared politics and initiatives, attempted to advance environmental protection and the science necessary to 'measure, monitor and manage' earth's systems. George was often called the father of the Landsat mission and its programs and in his role on the government's oversight committee in the House of Representatives, and a Chairman of the Space, Science and Technology committee over decades, Congressman Brown worked to set in motion a constellation of earth science research programs. One his collaborators with Landsat and its pioneering studies, research, data and unique digital databases of knowledge was Virginia Tower Norwood. Together George and Virginia, can be called the father and mother of Landsat and earth science imaging that is a generational gift enabling us, today's generation of scientists, the public and political/educational groups around the world and NASA/NOAA/USGS and international science and space programs to manage earth's living systems.

Earth Science / Earth Observing System

The Original NASA Mission Statement

50+ Years of Studying Planet Earth


Steven Schmidt, GreenPolicy360 Founder: In remembrance of George E. Brown, a special person and Congressional Representative from California who brought a physics and engineering background his three decades of leadership to environmental earth science programs created on his watch. George saw what others didn't really understand and when he showed me the original Mission Statement of NASA, I began to understand. Here is the key phrase again -- โ€œTo understand and protect our home planet..."


The Earth Observing Fleet of Satellites


GreenPolicy360 / Steven Schmidt: In the late 1960s I first discussed environmental protection, engineering and politics with my newly elected Congressman from East Los Angeles. At the time I was a high school student on the debate team and that year in California debate topics centered on nuclear weapons and proliferation. George E. Brown, my district's representative, was trained in physics and engineereering and was writing about international dangers of war and nuclear disaster, so I thought I'd meet with him and ask for his assistance in my debating research work. George and I began what became a long journey. In many ways George was my mentor and I believe he saw in me my generation's hope and youthful energy as we worked together. I was an activist/educator and professional whom he trusted in and with whom he could share his thoughts and agenda.

Until George's passing in 1999, I was fortunate to see inside what became the U.S. earth science space missions and beginnings as a visionary man took on the the great questions of our era. From atomic issues of deep science, energy, war and peace, the need for environmental protection, and climate research, all George's work was focused in the 60s/70s/80s and 90s in Congress as a Chairman and leader of budget/policy and oversight of these new challenges. George Brown's life faced the big issues of the nation and world. I saw up close the vision, goals and plans that George was putting into practice.

Earth Science Research from Space, that is, measuring and monitoring Earth Systems, Earth's living systems, was front of mind in the world of George E. Brown.

GreenPolicy360 and I have been tracking George's history and memory. Do read about this generational journey and feel free to share with your networks.

Some of the latest work from programs George was responsible for proposing, drafting enabling legislation, shepherding passage and presidential signatures approving the missions are now, some 50 years on, producing unique data that scientists are using to reveal and intelligently respond to our pressing 21st Century challenges and George would be more than please if he were here to see the vision, goals and plans in full realization.

The Earth Information Center is one of the more recent reveals. It is an amazing online open-source database. Open it up. Surf around (as we used to say in Southern California). The vision of our world, our planet's living systems is a gift to know, share and use to protect and preserve life, and quality of life. As planet citizens our responsibility is to step up and do our best to make a positive difference during each of our lives.

Earth Science Research from Space is yours now.

What is a "Global Stocktake"?

The global stocktake is a critical turning point when it comes to efforts to address climate change - it's a moment to take a long, hard look at the state of our planet and chart a better course for the future.


The Global Stocktake is a participatory, inclusive and transparent process. It consists of three main phases taking place over the course of two years: Phase 1: Information Collection and Synthesis This first phase is underway.

NASA Earth Science Missions


EOS

Earth Observing System


GreenPolicy360 siterunner: Remembering a first generation visionary who worked over decades to create a system of earth science through a multi-satellite missions


The Earth Observing System (EOS)

The mission of the Earth Observing System is a core element of the ongoing NASA earth science programs first envisioned and set in motion in the 1970s. The constellation of satellites that now comprise a connected matrix of ongoing earth imaging programs (see the latest here) came about as the U.S. Congress realized in the years following NASA's establishment that Planet Earth was central to NASA's work. The initial NASA mission statement spoke of this study of Planet Earth as a key goal of NASA programs. A new science, space and technology Congressional Committee was created to envision and oversee these programs and one of the first realizations about the need for earth science came about through the LANDSAT program (see here). A historic moment brought into existence digital mapping, that is, multi-spectral imaging of earth from an orbiting satellite in space, envisioned and designed to collect and 'save' data of earth's living systems. This databank was considered to be essential by committee member George E. Brown who, as a physicist and engineer, began his three-decade + career in Congress. George eventually became known for his "big science" initiatives. What few knew back then at the beginning was how essential this data would become as climate science came into the light (in 1977 and '78 with George's work central to the drafting and passage of the first National Climate Act.)

In the 1980s, the Earth Observing System (EOS) work began in earnest.

NASA's Project Science Office years later described its beginning with this statement:

>Results from early missions shed light on critical components of the Earth system while prompting further, more advanced investigations. The NASA Earth Observing System (EOS) program was conceived in the 1980s and began to take shape in the early 1990s. EOS is comprised of a series of coordinated polar-orbiting satellites designed to monitor and understand key components of the climate system and their interactions through long-term global observations. The EOS missions focus on the following climate science areas: radiation, clouds, water vapor, and precipitation; the oceans; greenhouse gases; land-surface hydrology and ecosystem processes; glaciers, sea ice, and ice sheets; ozone and stratospheric chemistry; and natural and anthropogenic aerosols.


NASA's Earth Observing System (EOS) Reference Handbook


In June 1992, the National Space Policy Council issued National Space Policy Directive and EOS became part of a global change observation system.

Continuity of satellite missions gathering data over years established what is known as a longitudinal trendline of observations, the goal set forward in the late 1970s and 80s with LANDSAT, weather satellites and many others in the first generation of environmental science research with space-based remote imaging. This long vision would empower scientists and others to measure and monitor dynamic changes over time, a critical factor in enabling policies to be drafted to manage earth's systems. George Brown was a key factor in these decisions. He saw, as did your GreenPolicy360 siterunner who was following his work through the years, that data and sharing of data would build educational resources, science and new opportunities. Previous military intelligence programs from space, for example, were revisioned/rethought and ideas such as a Global Positioning System GPS with all of navigational potential on earth came into being under President Reagan in the 1980s. Later in the 1990s under Democratic administration the Next Generation Operational Control System acted toward increasing GPS positional accuracy. New mapping and navigation tools, now in most all new cars, were results of these programs that George Brown helped set in motion saw coming into existence before his passing away in 1999.

The Terra satellite, the first of 26 satellites that have orbited or continue to obit as a formal part of the EOS progam was launched on Dec. 18, 1999. Terra (originally known as EOS-1) was designed for a five-year mission life, but continued to orbit for more than another decade.

George was alive as the launch of the Terra EOS program happened in December 1999. He knew that his mission, his work, was continuing on as a legacy.

Again, we at GreenPolicy360 tip our hat to the vision of Planet Citizen George E. Brown, a generational thinker and doer, mover and shaker...

' "It's all connected": What happens in the North doesn't stay in the North

Arctic warming is historic, the Planet climate is shifting


Scientists are warning that the Arctic is warming four times faster than the rest of the planet, and at a higher rate than previously thought, according to new research, while Antarctic ice is also diminishing.

The research on the Arctic, published in the academic journal Communications Earth and Environment, studies data as Arctic temperature estimates from satellite missions becomes available.


Earth Systems Science from Space


Scientists have for a long time known that the Arctic is heating faster than the rest of the planet, but have not agreed on a rate. The warming effect, along with long-term decline in sea ice levels, are considered two major indicators of climate change.

The most recent landmarkย Intergovernmental Panel on Climate Change signed off by 234 scientists from more than 60 countries estimated that the Arctic was only warming around twice as fast as the rest of the planet. Global temperatures have risen at least 1.1C since pre-industrial times.

High sea temperatures are also causing diminishing sea ice in Antarctica, as temperatures rise in the Bellinghausen, Amundell and Weddell seas.

The new research comes as record-breaking heat was experienced across parts of the globe last month (July 2022), which ranked one of the three hottest on record.

NASA Fiscal Year 2023 Budget Request

May 2022

GreenPolicy360: We are putting forward a proposal to restore the Earth Science provisions to the Mission Statement of NASA.

Journalist Andrew Revkin wrote about the removal of this initial provision that was an essential part of the beginning of NASA as a government agency. We believe that, although these provisions were 'silently' removed in 2006, they continue to playing an essential role in the missions of NASA and NASA's work.


NASA's continuing vision and mission - as of 2005.png


Here is what Andrew Revkin wrote some 15 years ago in 2006:

>Andrew Revkin / July 22, 2006 / NY Times

>โ€œTo understand and protect our home planet; to explore the universe and search for life; to inspire the next generation of explorers ... as only NASA can.โ€

>In February 2006, the phrase "to understand and protect the home planet" was quietly removed from the National Aeronautics and Space Administration (NASA)'s official mission statement.

>It is the first time since NASAโ€™s founding in 1958 that the mission statement does not explicitly include mention of the Earth.


Here is part of NASA Administrator Bill Nelson's testimony before the Senate oversight committee this past week:

INDEED A LOT OF PEOPLE THINK OF NASA AS THE SPACE AGENCY. DON'T FORGET TO THE FIRST A, AERONAUTICS. BUT ALSO, PEOPLE DON'T REALIZE IT IS ALSO THE POINT OF THE SPHERE ON CLIMATE AND CLIMATE CHANGE BECAUSE ALL THE MEASUREMENTS THAT ARE BEING MADE ARE DONE BY INSTRUMENTS THAT WE DESIGN, BUILD, LAUNCH AND MANY OF THEM WE OPERATE.

OVER THE COURSE OF THE NEXT DECADE WE ARE GOING TO HAVE A GREAT OBSERVATORY OF FIVE ADDITIONAL MAJOR SPACECRAFT THAT ALL OF THIS INFORMATION IS GOING TO BE PUT INTO A 3D COMPOSITE ON PRECISELY WHAT IS HAPPENING TO THE EARTH'S CLIMATE. WHAT'S HAPPENING TO THE WATER, TO THE LAND, TO THE ICE, TO THE ATMOSPHERE. WE ARE PUTTING UP AT THE END OF THIS YEAR A MISSION THAT IS GOING TO BE ABLE TO MEASURE FOR THE FIRST TIME THE ELEVATION OF THE STREAMS AND RIVERS AND LAKES, THE FRESHWATER. WE'VE BEEN ABLE TO MEASURE THE ELEVATION OF THE OCEANS, THE SALTWATER. WE ARE GOING TO BE ABLE TO FIND OUT VERY PRECISELY WHAT IS HAPPENING TO THE ICE.

ALL OF THIS AND WE HAVE THE SUPPORT OF THE WHITE HOUSE ON THIS AND WE HOPE WE WILL HAVE YOUR SUPPORT. WE ARE GOING TO CREATE IF YOU CAN ENVISION IN SPACE TERMS A MISSION CONTROL CENTER. IT'S GOING TO BE CALLED THE EARTH INFORMATION CENTER. IT'S GOING TO BRING ALL OF THIS DATA IN AND IT'S GOING TO BE DISPLAYED AND IT'S GOING TO BE AVAILABLE TO EVERYBODY, NOT JUST GOVERNMENT AT ALL LEVELS INCLUDING YOUR LOCAL COUNTY COMMISSION WHEN THEY ARE PLANNING, BUT IT'S GOING TO BE AVAILABLE TO SCHOOLS AND UNIVERSITIES AND THE PRIVATE SECTOR AS WELL AS TO WHAT IS HAPPENING AND THE CHANGES THAT ARE HAPPENING TO THE CLAIMANT.


Readers of GreenPolicy360 can look back at our founder's work with George E. Brown, who was instrumental as a leader in Congress for over 30 years and led Earth Science efforts, including advancing NASA's first generation of earth research from space.

Congressman Brown's point of view for over 30 yrs in Congress was that technology, science, data are guides necessary for smart policy decisions. Check out his record. George set in motion many of the programs and missions to accomplish multi generational envir protection goals that we have taken up and carried on...


Planet Citizens | Envisioning New Ways of Protecting Life


The Original Mission Statement of NASA provided Congressional intent and guidance to the first generation of space programs.

NASA is created and given a mission statement: โ€œTo understand and protect our home planet; to explore the universe and search for life; to inspire the next generation of explorers ... as only NASA can.โ€

George, if he were here, would've done everything within his power to protect the original mission statement, even as misinformation and denial are rampant these days ...

Landsat Memories, Looking Back at the Beginning of the U.S. Earth Sciences Mission

Measuring and Monitoring Earth's Life System and Resources from Space

Envisioning Environmental Protection with 'Eyes in the Sky'


SJS/GreenPolicy360 Siterunner: The U.S. Interior Department, the U.S. Geological Survey, NASA with the Congressional Science and Technology Committee (originally the Science and Astronautics Committee were responsible for building the original Landsat program (which overcame much opposition within the military). ERTS-1, the Earth Resources Technology Satellite, as the original Landsat satellite was officially first called, was 'greenlighted' to go as a real time earth observation mission in 1970. The vast digital database it gathered has proven over the years the wisdom of the visionaries who first proposed, drafted legislation creating, funding, then engineering, testing, launching and ably defending the Landsat mission from critics over the decades. Now the results are being re-considered for the unique value they provide in guiding policy discussion, debate and decisions. The Landsat library of imagery, millions of images, multispectrum observations of change on earth over the first fifty years of the mission's existence, are seen in a new light.


In the late 1960s and early 70s, Congressman George Brown on the Science and Technology Committee was pressing forward with NASA's development of the first array of earth science satellite missions. Near the top of his list of project missions was LANDSAT 1.

Representative Brown was out in front of "Big Science". In his decades on the House Science, Space & Technology Committee, he worked to expand the reach of science. He knew that good data enabled good policy decisions. He pressed for first-generation earth science satellites and ongoing earth monitoring missions and data sharing.


George E. Brown Jr

GreenPolicy360 Siterunner: "Remembering my friend George"


Among his many initiatives, George Brown was a key figure in proposing, establishing, and then saving the Landsat program and its unique 'open-access' database of Earth Science imaging. Later, when President Reagan attempted to end the Landsat mission budget and shut the Landsat program down, George Brown intervened and led the opposition. Landsat's earth science technology continued to be a model for all earth science research missions from space and is now moving into its fifth decade with Landsat 9.

What does the Earth look like from "out there?"

Pesquet: When you look at the Earth from the space station, it's absolutely magical. You're not that far away, so you still have a relatively close-up view. But you can see the curvature and you see the atmosphere. It glows in blue. It is absolutely breathtaking the first time you see it. It's the most beautiful scenery you could possibly imagine.

When you're on the Earth, you feel that everything is so vast, everything is endless. You have a hard time understanding how limited we are. Then, when you take a step back and you see the Earth in its entirety, you suddenly understand that we live in an oasis in the cosmos. All around us is nothing, no life, blackness, emptiness, absolutely nothing -- apart from this blue ball with everything we need to sustain human life, and life in general, which is absolutely fragile.


It makes you want to cherish the Earth and protect it, the more you see it from space.

'Virtual signs' worsening

Tipping points, deepening disaster


Researchers, part of a group of more than 14,000 scientists who have signed on to an initiative declaring a worldwide climate emergency, said that governments had consistently failed to address the root cause of climate change: "the overexploitation of the Earth".

Of 31 "vital signs"โ€”key metrics of planetary health that include greenhouse gas emissions, glacier thickness, sea-ice extent and deforestationโ€”they found that 18 hit record highs or lows.

Atmospheric Experiment of Humanity.jpg


The Earth's atmosphere does not abruptly end at any given height but becomes progressively thinner with altitude. The edge of most all of the atmosphere (80% approximately in the Troposphere) is not far above us.

The troposphere is one of five layers of the atmosphere surrounding the earth. The other four layers include the stratosphere, mesosphere, thermosphere, and exosphere. The troposphere is the lowest layer of the atmosphere, closest to the earth's surface. Its depth is different at different regions of the earth, being deeper in the warmer regions and shallower in the colder regions. The word 'troposphere' is derived from the Greek word 'Tropos' which means 'change'.

The troposphere is located closest to the earth, followed by the stratosphere, mesosphere, thermosphere, and the exosphere. The troposphere contains approximately 80% of the mass of the atmosphere of the Earth and 99% of the total mass of Earth's atmospheric water vapor.

The transitional area between the troposphere and stratosphere is called the tropopause. The jet stream or 'river of air' as it is also referred to, is located just below the tropopause and moves at approximately 250 miles per hour. The troposphere extends from the earth's surface to approximately 33,000 feet (6.2 miles) high. However in warm regions like the equator it can rise as high as 65,000 feet (12 miles). In colder regions like the north and south poles, it may rise only as high as 23,000 feet (4 miles). The troposphere is not heated directly from the sun. Instead, the sun heats the ground and the ocean and this heat is then radiated into the troposphere.

Despite the fact that only a small percentage of the troposphere's gas is carbon dioxide, this is the determining factor in the earth's temperature...

Satellite Monitoring of Methane from Space

Satellites Put the Worldโ€™s Biggest Methane Emitters on the Map

Now the companies and countries responsible for a powerful greenhouse gas wonโ€™t be able to hide from view

Orange and yellow pixels flash over American drilling heartlands around the Gulf Coast, New Mexico, and Pennsylvania. Dark red stretches across Middle East and China, while disturbing dots of color pop up around Greenlandโ€™s coast. This is the dangerous world of atmospheric methane emissions, one of the most powerful drivers of global warningโ€”and itโ€™s visible to the public for the first time.

GHGSat Inc. released a new methane map on October 21, 2020 that uses data from the companyโ€™s two satellites, which were launched earlier this year and can detect methane emitted by oil and gas wells, coal mines, power plants, farms and factories. Itโ€™s part of a wave of climate surveillance that will make it possible to hold countries and companies accountable for meeting targets to reduce and eventually eliminate planet-warming pollution.

Detecting pollution of shipping lanes and individual ships from space

For the first time ever, scientists using data from @CopernicusEU #Sentinel5P were able to detect nitrogen dioxide plumes from individual ships from space.


A past study estimated that shipping emissions are globally responsible for around 400 000 premature deaths from lung cancer and cardiovascular disease, and 14 million childhood asthma cases each year.

For this reason, during the past decade, efforts to develop international shipping emission regulations have been underway. Since January 2020, the maximum sulphur dioxide content of ship fuels was globally reduced to 0.5% (down from 3.5%) in an effort to reduce air pollution and to protect health and the environment. It is expected that the nitrogen dioxide emissions from shipping will also become restricted during the coming years.

Monitoring ships to comply with these regulations is still an unresolved issue. The open ocean covers vast areas, with limited or no capacity to perform local checks. This is where satellites, such as the Copernicus Sentinel-5P satellite, come in...

Claus Zehner, ESAโ€™s Sentinel-5P Mission Manager, commented, โ€œWe think that these new results demonstrate exciting possibilities for the monitoring of ship emissions in support of environmental regulation from space. Future planned satellite missions with improved spatial resolution, for example the Copernicus Anthropogenic Carbon Dioxide Monitoring satellites, should allow for the better characterisation of nitrogen dioxide ship emission plumes and, possibly, detection of smaller ship plumes.โ€

ECOSTRESS will address three overarching science questions:

How is the terrestrial biosphere responding to changes in water availability?
How do changes in diurnal vegetation water stress impact the global carbon cycle?
Can agricultural vulnerability be reduced through advanced monitoring of agricultural water consumptive use and improved drought estimation?

The ECOSTRESS mission will answer these questions by accurately measuring the temperature of plants. Plants regulate their temperature by releasing water through tiny pores on their leaves called stomata. If they have sufficient water they can maintain their temperature but if there is insufficient water their temperatures rise and this temperature rise can be measured with a sensor in space. ECOSTRESS will use a multispectral thermal infrared radiometer to measure the surface temperature. The radiometer that will be delivered to Houston for deployment on the International Space Station in 2018. The radiometer will acquire the most detailed temperature images of the surface ever acquired from space and will be able to measure the temperature of an individual farmers field.

2019 Arctic Report Card

The average annual land surface air temperature north of 60ยฐ N for October 2018-August 2019 was the second warmest since 1900. The warming air temperatures are driving changes in the Arctic environment that affect ecosystems and communities on a regional and global scale.

The Greenland Ice Sheet is losing nearly 267 billion metric tons of ice per year and contributing to global sea-level rise.

North American Arctic snow cover in May 2019 was the fifth lowest in 53 years of record. June snow cover was the third lowest.

Tundra greening continues to increase in the Arctic, particularly on the North Slope of Alaska, mainland Canada, and the Russian Far East.

Satellites to Monitor Air Pollution across the World, City by City, Region by Region

(May 2019) Air pollution monitoring revolutionized with launch of new satellite system

โ€ข https://finance.yahoo.com/news/climate-crisis-satellites-monitor-air-155129758.html


โ€œEmerging AI remote sensing techniques (intend) to hold every powerful polluter worldwide accountable ... better data ... puts most companies, governments, and environmentalists on the same side ... responsible, forward-thinking groups have started using advanced data to voluntarily slash emissions....โ€


Tracking damaging greenhouse gas emissions coming from every large power station in the world in real time

The system promises far greater accuracy and detailed emissions data for each power station, effectively reducing barriers to insight into the impacts of power generation, ensure accurate emissions data and bring new opportunities to hold companies to account.

The satellite network will observe the power plants from space, while AI technology will use the image processing algorithms to detect signs of power plant emissions.

OCO-3 News Coverage Should Have Been of a Globally Important Event

OCO-3 arrives at the International Space Station to begin its earth science-space mission. There's little to find in Media coverage on its real-world importance whether on Google News, Bing Search, Yahoo, Duck Duck Go, pick your international news sources...

Yet, in fact and substance, the science of OCO-3 is critically important. Earth Science. Measuring CO2. JPL-Caltech/NASA, scientific inquiry at its best. Essential data and baseline information critical for informed policy and decision-making (yet President Donald Trump tried to kill the launch of OCO-3 and related US FY2018 missions to measure and monitor CO2).

A global security story... National security... Existential threats ...

OCO-3 Arrives at the International Space Station

(Interview at JPL courtesy of the LA Times)

OCO-3 was built at the Jet Propulsion Laboratory for less than $100 million, using parts left over from its predecessor, OCO-2. Once the carbon observatory gets to the ISS, a robotic arm will mount it on the underside of the space station so it can keep a close eye on the carbon dioxide in Earthโ€™s atmosphere.

That will help scientists answer questions about how and why levels of the greenhouse gas fluctuate over days, months and years.

โ€œOur goal is to get really good data so we can make informed decisions about how to manage carbon and carbon emissions in the future,โ€ said Annmarie Eldering, the missionโ€™s project scientist at JPL.

Carbon dioxide makes up a tiny fraction of the molecules in our atmosphere โ€” roughly 400 parts per million. But seemingly small changes in the amount of carbon dioxide in the atmosphere have an outsized effect on the planetโ€™s temperature.

โ€œCarbon is really effective at trapping heat,โ€ Eldering said. โ€œEven changing the ratio from 300 parts per million to 400 parts per million makes a big difference.โ€

OCO-3 is so sensitive that it can detect changes as small as 1 part per million. So if CO2 levels go from 406 ppm one day to 407 ppm the next, the space-based observatory will record the increase.

Measuring and Monitoring Atmospheric Emissions

Detecting methane from space
"There has been quite a buzz around this unique advancement in space, and the valuable data it will provide on methane, a powerful greenhouse gas that accounts for a quarter of the warming our planet is experiencing today. Curbing anthropogenic methane emissions is one of the most efficient and economical options available to slow the rate of warming over the next few decades, while efforts continue to reduce CO2 emissions worldwide."





The Environmental Defense Fund (EDF) is planning to be the first environmental group to send its own satellite into space.
โ€œWe need good solid data so that we really can support global action on climate change, and weโ€™ve got to do it fast,โ€ says Steven Hamburg, the EDFโ€™s chief scientist.
The most detailed measurements currently available of atmospheric methane concentrations currently come from a sensor aboard the European Space Agencyโ€™s Sentinel-5P spacecraft, which launched in October 2017. The Tropospheric Monitoring Instrument provides global coverage at a resolution of nearly 50 square kilometres, but those measurements do not capture the dispersed sources of emissions from oil and gas fields.
Commercial firms have developed high-resolution sensors that can be placed aboard 10-centimetre-sided CubeSats to measure emissions from individual wells or other facilities. Those data are proprietary, however, and the measurements cannot be scaled up to the level of an entire oil and gas field.
The Environmental Defense Fund team is designing MethaneSAT to provide more-precise measurements, at a resolution of 1 square kilometre, with global coverage at least once a week.

Looking Back as We Turn from 2017 to a New Year

"This year has been an unequivocal disaster for the future of the planet. President Donald Trump has managed to take a wrecking ball to years' worth of hard work and painstaking negotiations. If not undone, our retreat from the Paris Climate Accords and the EPA's Clean Power Plan alone mean our planet's temperature will rise at a greater rate and our citizen's health will degrade. Other changes in environmental regulations on drilling and auto and appliance efficiency will only make matters worse."

Perhaps the thing that worries me the most is the massive deforestation underway in areas like Asia and Latin America. Countless trees and millions of square miles of jungle and forest have been removed to accommodate our desires for more -- more wood, more farmland, more pasture, more meat.

When I first looked down upon the Amazon rainforest in 2001, I saw vast areas of jungle and a wide and winding copper colored river that went on and on and on. A river that was impossible to miss and like no other on the planet. By 2011, however, the part that was most noticeable wasn't the river or the jungle but the large swaths of empty land.

From space, it looks empty because we are far away. We don't see the crops or the cattle but we do see the loss. We see the loss of an incredibly diverse ecosystem that once held endless possibilities for new medicines and other discoveries.

We see the loss of a home for so many species that will now have to learn to adapt and survive somewhere else -- or not. And we see the loss of a large amount of carbon, sequestered in a living and breathing ecosystem which created massive amounts of oxygen for all of us.

That carbon, once the giver of life to millions of species all over our planet, now has a new role: greenhouse gas. It will sit in our atmosphere as CO and CO2 for millennia, but in this case as an invisible blanket, warming our planet, changing our climate and creating a cataclysmic mess for future generations.

โ€œHigh-resolution earth imagery sources, beyond historic US/NASA/NOAA/ESA research from space, represent rich new troves of information...โ€ says David Johnston of Duke Universityโ€™s Nicholas School of the Environment. Johnson and his co-authors embrace satellite imagery โ€œas a legitimate data source that can supplement and even supplant traditional methods.โ€

The rapidly growing abundance and sophistication of satellite imagery and remote sensing data is about to change (the scientific fields of earth science)... thanks to a profusion of startup companies, including Planet, DigitalGlobe, Skybox Imaging (later purchased by Google and renamed Terra Bella), Urthecast, and LAND INFO Worldwide Mapping.

Trump Administration Budget Undercuts "Earth Science" at NASA

Vital Security Programs Cut / OCO-3 Mission to Study CO2 in Atmosphere Eliminated


The proposed NASA budget targets the agencyโ€™s work on environmental science, cutting funding for Earth science research grants. The cuts would go further by eliminating several missions that are in development, including PACE (Plankton, Aerosol, Cloud, ocean Ecosystem), which is intended to monitor and provide baseline data of the Earthโ€™s ocean and their health; the Orbiting Carbon Observatory 3, or OCO-3, an instrument to precisely monitor the carbon dioxide in our atmosphere, continuing the unique work of OCO-2; and the Climate Absolute Radiance and Refractivity Observatory, or CLARREO, pathfinder, which is to use a solar spectrometer to produce highly accurate climate projections.

*The Critical Importance of "EarthScience360" from Space

GreenPolicy360: The election of Donald Trump as US president delivers immediate crisis and a turning point. The president-elect's statements that climate change is a 'hoax' and environmental policies and programs, including NASA 'Earth Sciences', are impediments that need to be ended now assures tumult and a new level of threat to national and global security. Announced administration appointees, as of November 2016, and recent Congressional threats to deeply cut environmental protection and NASA 'Earth Science' budgets are warning signs of coming showdowns over the direction of the nation and the nation's priorities.

NASA scientists responsible for vital programs have been reluctant to speak publicly since the election but one anonymous NASA scientist is among the first to write online about the value of earth science research from space.

Anon: "We are the largest combined organization of scientists and engineers in the world dedicated to space-based observations of Earth, the Solar System, and the Universe. A huge part of our mission is to design and fabricate Earth-viewing satellites that track long-term changes in topography and climate. These satellites ensure that we have the most complete set of data available to not only predict how humanity's impacts will affect the Earth, but also understand how we can prepare and protect those most vulnerable to climate change and rising sea levels. As an example of our impact on the daily lives of people around the world, one of the satellites I previously worked on, Global Precipitation Measurement, is currently in Earth orbit tracking extreme weather events. Its data allows meteorologists to improve their forecasts of where hurricanes will strike and how intense they will be, as well as to identify the areas that are most prone to floods and landslides, so that we can give advanced warnings to those affected. This is just one of dozens of major Earth-observing satellites that NASA manages everyday.
"Today, we were shocked to hear of Trump's plan to scrap NASA's climate change research as part of a crack down on "politicized science". Among the scientific community, climate change is no more "politicized science" than the theory of gravity is. While his crackdown would mean that thousands of scientists and engineers at NASA Goddard would lose their livelihoods, it represents an even greater loss for the world. Without data continuity in our Earth observations, we will be blind to the ravages of climate change: to the deluges and droughts that might devastate crops, to the extreme weather events that destroy communities as the Earth continues to warm. We will not be able to develop the solutions that can prevent Earth's temperatures from rising to catastrophic levels. I urge you to implore your Congressional Representatives to not allow Trump's plan to happen. We cannot sit on the sidelines over the next four years: our future on this planet is at stake."

December 14, 2016

Speaking directly to threats to the value of earth science and earth science research from space, Governor Brown addressed the American Geophysical Union (AGU) Fall Meeting in California. The AGU annual gathering is the largest Earth and space science meeting in the world.

The AGU is an international scientific society that describes itself as "dedicated to promoting discovery in Earth and space science for the benefit of humanity."


Jerry Brown:

"We got the scientists. We got the lawyers. And we're ready to fight. We're ready to defend. And California is no stranger to this fight...

"California is the future. We are pioneering space...

"Now some people say they're going to turn off the satellites that are monitoring the climate... low-earth phenomena, the LANDSAT and all the various measuring satellites that we have...

"Well, I remember back in 1978 I proposed a LANDSAT satellite for California. They called me 'Governor Moonbeam' because of that. I didn't get that moniker for nothing.

"And if Trump turns off the satellites, California will launch its own (d-mn) satellites!"

GreenPolicy360 Siterunner: In the late 1960s and early 70s, Congressman George Brown on the Space and Technology Committee was pressing forward with NASA's development of the first array of earth science satellite missions. Near the top of his list of project missions was LANDSAT 1.

Representative Brown was out in front of "Big Science". In his decades on the House Science, Space & Technology Committee, he worked to expand the reach of science. He knew that good data enabled good policy decisions. He pressed for first-generation earth science satellites and ongoing earth monitoring missions and data sharing.


George E. Brown Jr


Among his many initiatives, George Brown was a key figure in proposing, establishing, and then saving the Landsat program and its unique 'open-access' database of Earth Science imaging when President Reagan attempted to shut Landsat down. Landsat was a model for all the following earth science research missions from space and is now moving into its fifth decade with Landsat 9.

A Successful Era in Climate Science

Calipso - Ten Years in Space (and Flying with the 'A-Train')

Since its launch in 2006, CALIPSO has orbited the Earth tirelessly, using its lasers to take more than 5.7 billion lidar (light detection and ranging) measurements probing the vertical structure and properties of clouds and other particles โ€” such as dust, sea salt, ash and soot โ€” in the air.

For atmospheric scientists, the ability to regularly and accurately examine clouds and particles at different heights was something new. Gathering that data over such a long time period has contributed to a scientific bonanza.

Also, scientists are able to combine CALIPSOโ€™s measurements with those of other Earth-observing satellites circling the globe in a cooperative path called the A-Train constellation. CALIPSO and CloudSat, a satellite containing a cloud-profiling radar, launched together on a Delta II rocket, now fly in formation with satellites named Aqua, Aura, Global Change Observation Mission-Water (GCOM-W) and Orbiting Carbon Observatory (OCO)-2.

Combining measurements from these A-Train satellites offers a clearer view of whatโ€™s happening in the atmosphere.

โ€œCALIPSO, in complement with the other instruments flying in the A-Train, has provided observations in areas that had never been observed before,โ€ said Pierre Tabary, program manager for atmosphere, meteorology and climate for CNES, the French space agency.

He said scientists have gained knowledge about clouds, and their impact on incoming solar radiation, as well as on infrared radiation coming from the Earthโ€™s surface, known as the greenhouse effect.

โ€œThere were no other instruments providing such observations before,โ€ Tabary said. โ€œAll those data have been used to improve our understanding of how climate works.โ€

More than 1,600 scientific and technical reports and published research papers have used CALIPSO data. The data are widely cited in reports from the Intergovernmental Panel on Climate Change", Tabary said, "a clear demonstration of what CALIPSO has brought to climate science."

DSCOVR is launched and on its way!

Godspeed DSCOVR... On February 12, 2015 the DSCOVR satellite with its EPIC cam and earth-science instrument package is on the way...

A million mile journey to its orbit, DSCOVR is scheduled to light up, go through its testing phases and begin delivering data to Earth in August, including near-real-time imaging of Earth provided online ...

We/GreenPolicy360 are cooperating with NASA DSCOVR mission managers and will be delivering a stream of home planet imagery and data as NASA/NOAA begin uploading EPIC-cam and instrument 'pictures of home'!


For GreenPolicy360, the centerpiece of the mission will be the EPIC cam images of Earth 360

First whole earth pictures to be delivered from deep space since 1972 -- images we are looking to share as a life message of our home planet.


Unprecedented accompanying data and imagery made available open source for โ€ช#โ€ŽEarthScienceโ€ฌ and climate/atmospheric monitoring.

โ—‹


It's been some time since December 7, 1972 when the only picture ever snapped by a human of the whole earth was captured -- our iconic "Blue Marble" -- Engineers that they are, NASA named that first planet citizen/astronaut-taken image -- AS17-148-22727

As we have been recalling the history, we haven't had returned to us a 'whole earth' image since 1972. Today, February 10, 2015, the Associated Press reports Sen. Bill Nelson, D-Florida, pointing out from Washington that there hasn't been a full, sunlit picture of the Earth since Apollo 17 in 1972 - NASA's last manned moon-landing mission. Subsequent images have been stitched together, the Senator explained, for composite shots. The Senator has an exceptional point of view as he was an astronaut -- In January 1986, Nelson spent six days orbiting Earth as a payload specialist aboard space shuttle Columbia. His NASA bio adds "The experience gave him a new perspective on the Earthโ€™s fragile environment and a greater appreciation of the importance of our nationโ€™s space exploration program."


The DSCOVR satellite launches into deep orbit with multiple missions -- to monitor space weather and, due to the satellite's orbital distance from Earth (1 mil miles), DSCOVR will be sending back daily images of the 'whole earth' via its EPIC image-taking system and via its NISTAR system measuring earth's earth's temperature, our "radiation balance" ("albedo").

NASA OCO Satellite Sends Back Most Detailed CO2 View Ever

Initial round of CO2 data is released...

First full set of CO2 data made available in March 2015 for scientists and public to download and explore.


More on the history-making OCO-2 / Orbiting Carbon Observatory

According to JPL scientists: "Where OCO-2 really excels is the sheer amount of data being collected within a day, about one million measurements across a narrow swath... For fluorescence, this enables us, for the first time, to look at features on the five- to 10-kilometer scale on a daily basis." SIF can be measured even through moderately thick clouds, so it will be especially useful in understanding regions like the Amazon where cloud cover thwarts most spaceborne observations."

The changes in atmospheric carbon dioxide that OCO-2 seeks to measure are so small that the mission must take unusual precautions to ensure the instrument is free of errors. For that reason, the spacecraft was designed so that it can make an extra maneuver. In addition to gathering a straight line of data like a lawnmower swath, the instrument can point at a single target on the ground for a total of seven minutes as it passes overhead. That requires the spacecraft to turn sideways and make a half cartwheel to keep the target in its sights.

The targets OCO-2 uses are stations in the Total Carbon Column Observing Network (TCCON), a collaborative effort of multiple international institutions. TCCON has been collecting carbon dioxide data for about five years, and its measurements are fully calibrated and extremely accurate. At the same time that OCO-2 targets a TCCON site, a ground-based instrument at the site makes the same measurement. The extent to which the two measurements agree indicates how well calibrated the OCO-2 sensors are.

Additional maps released recently showed the results of these targeting maneuvers over two TCCON sites in California and one in Australia. "Early results are very promising," said Paul Wennberg, a professor at Caltech and head of the TCCON network. "Over the next few months, the team will refine the OCO-2 data, and we anticipate that these comparisons will continue to improve."

Phytoplankton are essential ecosystems of the seas. They are floating, drifting, plant-like organisms that harness the energy of the Sun, mix it with carbon dioxide that they take up from the atmosphere, and turn it into carbohydrates and oxygen.

Scientific estimates speak of approximately half the oxygen in the Earth's atmosphere being the result of plankton photosynthesis and phytoplankton are critical to the marine food web, being the primary producers of food in the oceans, from phytoplankton to zooplankton to fish and shellfish to whales.

Like plants and trees on land, "phytoplankton give us a lot more than food". Whether the current science estimates that 50 or 80 percent of the oxygen in our atmosphere has been produced by phytoplankton, the health of the blue-green ocean life is essential for sustainable ocean ecosystems. The tiniest of living organisms exert an outsized influence on the planet.

Phytoplankton rapidly disappearing

Loss of mini marine plants at base of food web threatens seaโ€™s ecology

A rapid loss of phytoplankton threatens to turn the western Indian Ocean into an โ€œecological desert,โ€ a new study warns. The research reveals that phytoplankton populations in the region fell an alarming 30 percent over the last 16 years.

A decline in ocean mixing due to warming surface waters is to blame for that phytoplankton plummet, researchers propose online January 19 in Geophysical Research Letters. The mixing of the oceanโ€™s layers ferries phytoplankton nutrients from the oceanโ€™s dark depths up into the sunlit layers that the mini plants inhabit.

The loss of these microbes, which form the foundation of the ocean food web, may undermine the regionโ€™s ecosystem, warns study coauthor Raghu Murtugudde, an oceanographer at the University of Maryland in College Park.

โ€œIf you reduce the bottom of the food chain, itโ€™s going to cascade...โ€

New NASA ERA

Sept 08, 2014 - NASA opens a new era in its exploration of our home planet with the launch of the first in a series of Earth science instruments to the International Space Station, Earth-observing instruments to be mounted on the exterior of the #ISS. ISS-RapidScat will monitor ocean winds for climate research, weather predictions and hurricane monitoring. The second instrument is the Cloud-Aerosol Transport System (CATS), a laser instrument that will measure clouds and the location and distribution of pollution, dust, smoke, and other particulates in the atmosphere. Look closer at the array of instruments #RapidScat #EarthRightNow

The Arctic Ice Is Melting: Why?

Permafrost Loss, Potential Impacts, Time to Measure


2016

fig1.gif

Scientists estimate that five times as much carbon might be stored in frozen Arctic soils โ€” permafrost โ€” as has been emitted by all human activities since 1850. This worries people who study global warming. While emissions from permafrost currently account for less than 1 percent of global methane emissions, some researchers think this could change in dramatic ways as the world warms and that carbon-rich frozen soil breaks down.


Permafrost.jpg


The map above, based on data provided by the National Snow and Ice Data Center, shows the extent of Arctic permafrost. Any rock or soil remaining at or below 0 degrees Celsius (32 degrees Fahrenheit) for two or more years is considered permafrost.

Continuous permafrost, which occurs in the coldest areas, refers to areas where frozen soil underlies more than 90 percent of the surface. Discontinuous permafrost occurs in slightly warmer areas, where frozen soils underlie 50 to 90 percent of the surface, while certain features such as rivers and south-facing slopes may be ice-free. In areas with sporadic permafrost, frozen soils underlie 10 to 50 percent of the surface. In areas with isolated permafrost, frozen soils underlie less than 10 percent of the surface, usually only occurring in depressions or north-facing slopes.

As Earth Warms, NASA Targets 'Other Half' of Carbon, Climate Equation

As Earth Warms, NASA Targets 'Other Half' of Carbon, Climate Equation 797x448.jpg


Permafrost Threatened

Using statistically modeled maps drawn from satellite data and other sources, U.S. Geological Survey scientists have projected that the near-surface permafrost that presently underlies 38 percent of boreal and arctic Alaska would be reduced by 16 to 24 percent by the end of the 21st century under widely accepted climate scenarios. Permafrost declines are more likely in central Alaska than northern Alaska.

Northern latitude tundra and boreal forests are experiencing an accelerated warming trend that is greater than in other parts of the world. This warming trend degrades permafrost, defined as ground that stays below freezing for at least two consecutive years. Some of the adverse impacts of melting permafrost are changing pathways of ground and surface water, interruptions of regional transportation, and the release to the atmosphere of previously stored carbon.

โ€œA warming climate is affecting the Arctic in the most complex ways,โ€ said Virginia Burkett, USGS Associate Director for Climate and Land Use Change. โ€œUnderstanding the current distribution of permafrost and estimating where it is likely to disappear are key factors in predicting the future responses of northern ecosystems to climate change.โ€


โ—‹ โ—‹ โ—‹ โ—‹ โ—‹ โ—‹ โ—‹ โ—‹ โ—‹ โ—‹ โ—‹ โ—‹ โ—‹ โ—‹


A severe threat to tundra is global warming, which causes permafrost to melt. The melting of the permafrost in a given area on human time scales (decades or centuries) could radically change which species can survive there.

Another concern is that about one third of the world's soil-bound carbon is in taiga and tundra areas. When the permafrost melts, it releases carbon in the form of carbon dioxide and methane, both of which are greenhouse gases. The effect has been observed in Alaska. In the 1970s the tundra was a carbon sink, but today, it is a carbon source. Methane is produced when vegetation decays in lakes and wetlands.

The amount of greenhouse gases which will be released under projected scenarios for global warming have not been reliably quantified by scientific studies, although a few studies were reported to be underway in 2011. It is uncertain whether the impact of increased greenhouse gases from this source will be minimal or massive.

What Happens in the North, Doesn't Stay in the North

A self-reinforcing positive feedback loop is akin to a "vicious circle": It accelerates the impacts of anthropogenic climate disruption (ACD). An example would be methane releases in the Arctic. Massive amounts of methane are currently locked in the permafrost, which is now melting rapidly. As the permafrost melts, methane - a greenhouse gas 100 times more potent than carbon dioxide on a short timescale - is released into the atmosphere, warming it further, which in turn causes more permafrost to melt, and so on...

Predicted rate of temperature change in Arctic

Arctic temperatures are expected to increase at roughly twice the global rate. The Intergovernmental Panel on Climate Change (IPCC) will in their fifth report establish scenarios for the future, where the temperature in the Arctic will rise between 1.5 and 2.5ยฐC by 2040 and with 2 to 7.5ยฐC by 2100. Estimates vary on how many tons of greenhouse gases are emitted from thawed permafrost soils. One estimate suggests that 110-231 billion tons of CO2 equivalents (about half from carbon dioxide and the other half from methane) will be emitted by 2040, and 850-1400 billion tons by 2100. This corresponds to an average annual emission rate of 4-8 billion tons of CO2 equivalents in the period 2011-2040 and annually 10-16 billion tons of CO2 equivalents in the period 2011-2100 as a result of thawing permafrost. For comparison, the anthropogenic emission of all greenhouse gases in 2010 is approximately 48 billion tons of CO2 equivalents. Release of greenhouse gases from thawed permafrost to the atmosphere may increase global warming.
