List of Scientific Changes:
1.Updates to the snowfall rate (SFR) algorithm software including (1) Extreme Gradient Boosting (XGB) machine learning Snowfall Detection algorithms for JPSS-2/NOAA-21, NOAA-20, S-NPP, NOAA-19, Metop-C and Metop-B, (2) updated Neural Network machine learning Ice Water Path initialization and SFR bias correction for JPSS-2/NOAA-21, NOAA-20, S-NPP, NOAA-19, Metop-C and Metop-B, (3) new SFR low limit set at 0.05 mm/h and high limit at 6 mm/h, and (4) Metop-A processing removed.
2.Implementation of a new and up to date higher-resolution (0.05 degree lat/lon) land/water surface type database derived from global VIIRS data. The surface type at each satellite observation location also accounts for the satellite field of view (FOV) size. This replaces the previous and out of date 1/6th degree resolution database.
