EOSDIS support for the advanced spaceborne thermal emission andreflection radiometer (ASTER),

摘要

Abstract: The end-to-end ground data system supporting the advanced spaceborne thermal emission and reflection radiometer (ASTER) consists of elements provided by both Japan ASTER Ground Data System and the highly distributed Earth Observing System Data and Information System (EOSDIS). These two systems must interoperate to provide complex mission operations support and process high-rate (approximately 8 Megabits/sec) data into standard level 1, level 2 and higher data products. The EOS Data and Operations System (EDOS) will provide ground data capture, rate buffering, and level 0 data processing. The EOS Operations Center will provide the operational interface between the Japanese Instrument Control Center and the spacecraft and will monitor the instrument health and safety. The Land Processes Distributed active Archive Center (DAAC) at the EROS Data Center will produce higher-level products based on software provided by the ASTER Science Team and systems provided by the EOSDIS Core System. Higher-level data product quality assurance, as well as U. S. Science Team support for instrument scheduling, will be performed at a science computing facility located at the Jet Propulsion Laboratory. All of these elements are being developed together to assure that this international mission produces data which will serve the needs of the science community. !2
