The five instruments, Visible-InfraRed Imaging Radiometer Suite(VIIRS), Cross-track Infrared Sounder(CrIS), Advanced Technology Microwave Sounder ATMS and Ozone Mapping and Profiler Suite (OMPS), Clouds and the Earth s Radiant Energy Suite (CERES), on the NPOESS Preparatory Mission(NPP) will provide 30 data products to two primary user communities; operational users in the weather and environmental conditions forecasting communities requiring guaranteed access to real-time data and scientific users primarily interested in studying longer-term climate processes. This presentation will focus on the NPP data products that provide data continuity between past, present and future satellite instruments. The data product requirements, algorithm development and product validation processes will be presented.
