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

About ICVS LTM

An operational Integrated Calibration and Validation System (ICVS) for satellite instrument Near-Real Time (NRT) performance and data quality monitoring to support all NOAA weather satellite missions.
ICVS is an important monitoring tool for level 1b (L1b) or Sensor Data Records (SDRs), and is used by OSPO, NWS, ECMWF, EUMETSAT, NASA, Air Force, NAVO, as well as STAR scientists (especially the raadiance or SDR teams).

ICVS LTM Vision

ICVS is expected to bring together all operational 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), and make the radiances highly traceable among a constellation of global satellites in both polar and geostationary orbits.

ICVS LTM Objective

Establish an ICVS LTM platform for SNPP, JPSS, NOAA legacy POES instrument performance and data quality monitoring in NRT mode to support NOAA, especially JPSS SDR and EDR Cal/Val missions.

ICVS LTM Key Components

On-orbit and prelaunch instrument characterization and long-term monitoring of instrument performance for JPSS and legacy POES.
Top instrument and SDR product quality matrices for JPSS ATMS, VIIRS, OMPS and CrIS.
Inter-satellite calibration of radiances using the simultaneous nadir overpass (SNO), double difference (DD), and 32-day running mean direct bias methods.
