Advances in STAR Integrated Calibration/Validation System (ICVS) for Instrument Status, Data Quality, and Application Monitoring

The development of Integrated Calibration/Validation System (ICVS) at NOAA/Center for Satellite Application and Research (STAR) provides a platform for both satellite calibration scientists and engineers to better support NOAA operational environmental satellite calibration/validation and instrument maintenance activities. The near real time (NRT) critical spacecraft and onboard instruments health status and operational status data are analyzed and visualized by different temporal scales. The individual instrument performance is evaluated using SI traceable assessment method channel by channel. Any instrument anomaly will trigger automatic warning messaging system to alert a group of calibration scientists and instrument engineers for immediate troubleshooting and impact assessment to minimize the impact for NOAA daily operations. Meanwhile, satellite data users can obtain NRT information on satellite data product quality. Both Sensor Data Records (SDRs a.k.a. Lever 1) data and Environmental Data Records (EDRs a.k.a. Lever 2) data are projected to global maps and post in STAR ICVS website for public access. The statistical analysis of data quality by different temporal and spatial scales is another product generated and updated from the launch of satellite to build up the long term trending capability. STAR ICVS system also provides high resolution imagery products from latest generation visible instruments, such as VIIRS onboard polar-orbiting Suomi NPP satellite and AHI/GOES imager onboard geostationary Himawari8/GOES satellites, to monitor severe weather events. Reprocessing data quality trending is another function being added to ICVS. The Suomi NPP SDR life-cycle reprocessing data products have been generated for preliminary assessment. ICVS-Reprocessing site will host all SDR reprocessing related documents and coefficients for data users. Another new capability being added to ICVS is the NWP experiments testbed. Updates in both NWP model and satellite data can be tested and evaluated in such testbed immediately to provide better support to NWP users when satellite data are utilized for NOAA missions. ICVS has passed the pre-operational testing for JPSS-1 and GOES-R missions and also transitioned from NOAA/STAR to NOAA/OSPO for 24/7 operations.
