Earthdata powered by EOSDIS (Earth Observing System Data and Information System) is a key core capability in NASA’s Earth Science Data Systems Program. It provides end-to-end capabilities for managing NASA’s 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 (Level 0) processing. These capabilities, constituting the EOSDIS Mission Operations, are managed by the Earth Science Mission Operations (ESMO) Project. NASA network capabilities transport the data to the science operations facilities. EOSDIS uses the metadata and service discovery tool Earthdata Search https://search.earthdata.nasa.gov/ (formerly: REVERB).
EOSDIS is designed as a distributed system, with major facilities at data centers located throughout the United States. These institutions are custodians of EOS mission data and ensure that data will be easily accessible to users. The EOSDIS data centers process, archive, document, and distribute data from NASA's past and current Earth-observing satellites and field measurement programs. Acting in concert, the data centers provide reliable, robust services to users whose needs may cross the traditional boundaries of a science discipline, while continuing to support the particular needs of users within the discipline communities.For more information about the EOSDIS data centers see https://earthdata.nasa.gov/about/daacs
