The Suomi National Polar Orbiting Partnership (SNPP) and National Oceanic and Atmospheric Administration (NOAA-20) satellites’ Dual Ground Processing Systems and the Algorithm Change Processes (ACPs) That Maintain Their Operational Algorithms

The Suomi National Polar Orbiting Partnership (S-NPP) and National Oceanic and Atmospheric Administration (NOAA-20) satellites were successfully put into orbit on October 28, 2011 and November 18, 2017 respectively, carrying the following sensors: the Visible Infrared Imaging Radiometer Suite (VIIRS), Cross-Track Infrared Sounder (CrIS), Advanced Technology Microwave Sounder (ATMS) and Ozone Mapping and Profiler Suite (OMPS). The Interface Data Processing Segment (IDPS) and S-NPP Data Exploration (NDE) systems are two ground-based systems that process raw satellite data into the data products that are used by local and international government agencies, educational institutions, NOAA line offices the general public for critical climactic, meteorological, solar and oceanographic applications. The Joint Polar Satellite System (JPSS) project’s scientists and engineers document, monitor and fix errors in software code or documentation by following the Algorithm Change Process (ACP) to ensure the success of the S-NPP and NOAA-20 missions by making sure that the best data products are being provided to users. This poster will outline the IDPS and NDE systems’ ACPs from initial concept to approval for incorporation into the operational code while giving an overview of both ground processing systems and their use for delivering quality operational scientific data.
