The NPOESS Direct Readout Mission for Societal Benefit - GEOSS

摘要

The United States National Polar-orbiting Operational Environmental Satellite System (NPOESS) will provide Earth observations in both X-band and L-band direct broadcasts (DB) to the global direct readout (DRO) community. NPOESS capabilities provide the Oceanic regions of the world with the ability to assess their regional environments from space in near-real time by providing DRO capabilities for 41 HRD environmental data records (EDRs) to include imagery, and relays from ARGOS Advanced Data Collection System (A-DCS) sensor. Additionally, NPOESS provides within the direct broadcast links dynamic mission support data (MSD) which updates more quickly than can be accommodated through thrice annual software releases. MSD included within the links include weather forecast model parameters and algorithm processing coefficients. The NPOESS data processing software will be made available free of charge2 to the global community. Thus the NPOESS DRO mission will allow regional oceanic communities to compile knowledge of their local environments by having an up to date understanding of developing weather systems for disaster monitoring, an understanding of land and ocean environmental trends, and in-situ measurement retrieval from A-DCS sensors. This information interpreted and understood by experts of the region allows for significant contributions to the Earth Observation System of Systems (GEOSS) goals and mission that are not otherwise possible within the large oceanic community with limited communication resources.
