Distributed Active Archive Center

The Distributed Active Archive Centers (DAAC) are part of NASA's Earth Observing System Data and Information System (EOSDIS). DAACs process, archive, document, and distribute data from NASA's past and current Earth Observing System (EOS) satellites and field measurement programs. Each of the twelve data centers serves one or more specific Earth science disciplines and provides its user community with data products, data information, user services, and tools unique to its particular science.
