1st light! OCO-2 announces their data!

The newly launched Orbiting Carbon Observatory is now at the front of the international “Afternoon Constellation,” the “A-Train” of Earth-observing satellites in orbit. Their synchronized collection of data is a first and advances #earthmonitoring with a qualitative, quantum leap. Go we go!! Orbiting Carbon Observatory And while the A Train rolls on in the sky, maybe you'd like to listen to old but always good Duke Ellington's A Train ;-)

The image [spectra image below] shows some of the first data taken by OCO-2 as it flew over Papua-New Guinea forests on August 6, 2014. Each plot shows three different spectra, or wavelength, observed by the satellite’s spectrometers: 760 nanometers (atmospheric oxygen), 1610 nanometers (carbon dioxide), and 2060 nanometers (carbon dioxide).

As OCO-2 flies over Earth’s sunlit hemisphere, each spectrometer collects a frame three times per second (a total of about 9,000 frames from each orbit). Each frame is divided into eight spectra that record the amount of molecular oxygen or carbon dioxide over adjacent ground footprints, each of which is about 2.25 kilometers (1.39 miles) long and a few hundred meters wide. When displayed as an image, the spectra appear like bar codes. The dark lines indicate absorption by molecular oxygen or carbon dioxide.

“The initial data from OCO-2 appear exactly as expected [the scientists applaud here!]; the spectra lines are well resolved, sharp, and deep,” said OCO-2 chief architect and calibration lead Randy Pollock of NASA’s Jet Propulsion Laboratory.

“We still have a lot of work to do to go from having a working instrument to having a well-calibrated and scientifically useful instrument, but this was an amazingly important milestone.”

To put the spectra in context, this natural-color image shows the cloudy, forested scene below OCO-2 just minutes after it collected its data.

The color image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite, which flies in the A Train orbit.
