STAR Integrated Calibration/Validation System (ICVS) - Near Real Time (NRT) Monitoring

About ICVS

• Integrated Calibration and Validation System (ICVS) is an operational system to support NOAA operational weather satellite missions for satellite instrument Near-Real Time (NRT) status, performance, and science data quality monitoring and evaluation.
• ICVS is a mission critical instrument calibration/validation tool for Level 1b (L1b) or Sensor Data Records (SDRs) data quality assurance, and is daily used by NESDIS/STAR Cal/Val SDR science team, NESDIS/OSPO, NOAA/NWS, NASA, Air Force, Naval FNMOC, NAVO, as well as ECMWF and EUMETSAT satellite data users.
• ICVS brings together all NOAA operational weather satellite instruments, from Suomi National Polar-orbiting Partnership (SNPP), Joint Polar Satellite System (JPSS), NOAA legacy Polar Operational Environmental Satellites (POES), and Geostationary Operational Environmental Satellites (GOES), to make the satellite science data highly consistent and traceable among a constellation of global satellites observations in both low earth orbit (LEO) and geostationary earth orbit (GEO).

ICVS Key Components

1. NOAA operational weather satellite (JPSS, GOES, and legacy POES) spacecraft and aboard instrument health status and performance near real time monitoring modules, as well as an automatic spacecraft and instrument anomaly alert unit.
2. NOAA operational weather satellite science data product (L1b radiance, TDR/SDR, and GEO) quality near real time monitoring modules, including Quality Flag, Obs-Sim bias, and LEO-LEO/LEO-GEO inter-satellite/inter-sensor bias evaluation tools, as well as a radiance/SDR data quality degradation automatic alert unit.
3. NOAA operational weather satellite severe events, such as hurricane, flooding, et.al., watch using satellite near real time data observation.

ICVS Highlights

1. Monitoring 40+ instruments aboard multiple satellites with 7000+ monitoring products updated in neal real time through ICVS website to support NOAA critial missions since the launch of S-NPP in 2011.
2. Supporting quick instrument anomaly troubleshooting and solutions by instrument scientist and engineer based on various instrument status and data quality monitoring products.
3. Capturing major events, such as hurricanes, floodings, heatwaves, etc., happening worldwide in near real time with SDR images, animations, etc.
4. Providing a platform for future LEO satellite missions (e.g., QuickSounder, JPSS-3, JPSS-4, et. al.) pre-launch readiness activities.
