Description:To provide near-real time monitoring of Suomi-National Polar-orbiting Partnership (S-NPP) and NOAA-20 data inter-sensor biases, this study extends the Geosynchronous Equatorial Orbit – Low-Earth Orbit (GEO-LEO) intercalibration method established in [1] to the Visible Infrared Imaging Radiometer Suite (VIIRS) Sensor Data Record (SDR) data at six reflective solar bands (RSBs) and three thermal emissive bands (TEBs) bands via the STAR Integrated Calibration and Validation System (ICVS) framework. The Geostationary Operational Environmental Satellite (GOES) Advanced Baseline Imager (ABI) is used as a transfer to calculate double difference (DD) of VIIRS-ABI Simultaneous Nadir Overpass (SNO) pairs for the S-NPP and NOAA-20 VIIRS SDR cross-calibration biases. A series of sensitivity analyses on the dependence of the results to view geometries, spectral difference corrections, latitudinal variation, and cloud screening are conducted for more accurate bias estimations. The findings are further verified by the other independent approaches, namely the 32-day average difference method (32Day-AD) [2] and DD with radiative transfer model as a transfer (RTM-DD) method.
