Algorithms for various sensors aboard the JPSS-1 satellite are constantly updated to include the latest research on sensor technology as well as correcting any anomalies and oversights within the current version of the algorithms. These include both Sensor Data Record (SDR) algorithms as well as Environmental Data Records (EDR) algorithms. All the JPSS-1 SDR algorithms are processed in the Interactive Data Processing Segment (IDPS) system designed and maintained by Raytheon. The Algorithm Development Library (ADL) Block 2.1 is an updated offline test system developed by Raytheon to mimic the operational system. The center for Satellite Applications and Research (STAR) Algorithm Scientific Software Integration and System Transition Team (ASSISTT) facilitates research to operation (R2O) activities for JPSS-1 algorithms using ADL. The activities include integrating algorithm changes made by the scientists, testing the changes, evaluating the results and updating the associated documentation. The current ADL Block 2.1 version (MX6) works effectively on CentOS 7.0 or higher operating systems. In this version, several updates (OMPS TC and NP SDR corner geolocation, turning off of CrIS spike detection and correction, OMPS NP transient smear correction) have been implemented. In this presentation, the process of testing and integration activities with the updated MX6 version will be shown for weekly dark table updates for both OMPS Nadir Mapper (NM) and Nadir Profiler (NP) instruments and for both SNPP and JPSS-1 (J01) satellites. Bi-weekly updates are also made to Wavelength and Solar tables for OMPS NP for both SNPP and JPSS-1 satellites. These updates are submitted within the software package to be examined through another level of functional tests and verified by the Data Products Engineering and Services (DPES) team for operational implementation. Details of the process of integration and evaluation of OMPS algorithms as well as algorithms for other JPSS-1 instruments will be discussed.
