The EOS data and information system

The Earth Observing System (EOS) is proposed as a 1991 new initiative by NASA as part of the Mission to Planet Earth. One of the key components of the EOS program is the EOS Data and Information System (EOSDIS). Two independent Phase B studies of EOSDIS were conducted from January 1989 through April 1990. Some of the key challenges faced by EOSDIS are: satisfying the data and information needs of a diverse multidisciplinary scientific community integrating product generation algorithms for over two dozen instruments, keeping up with an orbital average data rate of over 50 Mb/sec and assuring prompt generation of standard products, reprocessing data as product generation algorithms change, and storing, and managing information about tens of Petabytes of data over the 15-year life of the mission.
