Architecture and design of storage and data management for the NASA Earth observing system Data and Information System (EOSDIS)

Mission to Planet Earth (MTPE) is a long-term NASA research mission to study the processes leading to global climate change. The EOS Data and Information System (EOSDIS) is the component within MTPE that will provide the Earth science community with easy, affordable, and reliable access to Earth science data. EOSDIS is a distributed system, with major facilities at eight Distributed Active Archive Centers (DAACs) located throughout the United States. At the DAACs the Science Data Processing Segment (SDPS) will receive, process, archive, and manage all data. It is estimated that several hundred gigaflops of processing power will be required to process and archive the several terabytes of new data that will be generated and distributed daily. Thousands of science users and perhaps several hundred thousand nonscience users will access the system.
