Earth Observation System Data and Information System - NASA EOS

NASA's Earth Observation System Data and Information System (EOSDIS) comprises elements including Distributed Active Archive Centers, Science Investigator-led Processing Systems, and web infrastructure.

NASA's Earth Observing System Data and Information System (EOSDIS) is a key core capability in the Earth Science Data Systems (ESDS) Program. It provides end-to-end capabilities for managing NASA Earth science data from various sources — satellites, aircraft, field measurements, and various other programs.

For the EOS satellite missions, EOSDIS provides capabilities for command and control, scheduling, data capture and initial processing. These capabilities, constituting the EOSDIS Mission Operations, are managed by NASA's Earth Science Mission Operations (ESMO) Project. NASA network capabilities transport the data to the science operations facilities.

The Earth Observation System (EOS) is continuing to be updated.

As noted by NASA, all Earth Science Data Systems (ESDS) Program web properties will be consolidated into the Earthdata website by the end of 2026.

Introduction to the Web Unification Project

The Web Unification Project is driven by the 21st Century Integrated Digital Experience Act (IDEA) signed into law in 2018. The IDEA Act requires all agencies in the executive branch to ensure their websites are compliant with Section 508 of the Rehabilitation Act of 1973, have a consistent look and feel, are searchable, secure, mobile-friendly, and without duplicative information. This motivation was followed up with a mandate from the NASA Earth Science Data Systems (ESDS) Program Executive to unify all ESDS-funded public-facing web properties into the Earthdata domain.

Background of EOSDIS

Today, many entry points lead to NASA Earth science dataset landing pages/data collections across the program. Since 1994, the Earth Observing System Data and Information System (EOSDIS) has provided end-to-end capabilities for managing this data archive through interconnected nodes across the United States. Each node has a website that represents a Science Investigator-led Processing System (SIPS) or a Distributed Active Archive Center (DAAC) that houses access to data and information unique to an Earth science discipline, platform, or instrument. There are also specialty websites that focus on certain data properties such as near real-time (LANCE) or fire data (FIRMS). These sites are the predominant focus of the Web Unification project.

The New Earthdata Website

The unified Earthdata website design launched at earthdata.nasa.gov in October 2024. Some of the data center sites were a part of the new site with the first launch. The remaining public-facing ESDS Program web properties will migrate into the new domain over the next two years. The projected completion date is the end of 2026.

Site users will be able to find, access, and visualize NASA Earth science data through text search, science topic, observation method, data resolution, data format, DAAC, SIPS, or data processing level.
