About the Data System (Purpose, Audience): The Earth Observing System Data and Information System (EOSDIS) manages and distributes data products through the Distributed Active Archive Centers (DAACs). The centers process, archive, document, and distribute data from NASA’s past and current research satellites and field programs. Each center serves one or more specific Earth science disciplines and provides data products, data information, services, and tools unique to its particular science. The Atmospheric Science Data Center is responsible for processing, archival and distribution of NASA Earth science data in the areas of radiation budget, clouds, aerosols, and tropospheric chemistry. It is unique among NASA data centers in the size of its archive, cutting edge computing technology and full range of data services.

Data Summit Presentation:

History: The Data Centers were established in 1991 to support the Earth Observing System as part of NASA’s Earth Science Enterprise and the U.S. Global Change Research Program, and is part of the Earth Observing System Data and Information System (EOSDIS).
