NOAA-Unique Combined Atmospheric Processing System (NUCAPS) data from CrIS and ATMS on NOAA-20 can give temperature and moisture information in regions otherwise lacking data. How well do those fields estimate the actual distribution of temperature and moisture? The toggle above compared visible imagery with gridded fields of temperature and moisture from NUCAPS from...

NUCAPS profiles derived from CrIS and ATMS data on NOAA-20 provide model-independent estimates of atmospheric thermodynamics globally, including, for this case over the central Pacific Ocean, in regions otherwise bereft of data.  NUCAPS lapse rates show a minimum in stability in low-levels in between two cloud features; the region includes...

An uncommon somewhat clear day on 20 February 2021 allowed VIIRS on Suomi-NPP to provide a true-color image of all 5 Great Lakes. The true-color image above is shown in a toggle with GOES-16 “Snow-Ice” Band 5 near-infrared data (1.61 µm) that allows for discrimination between clouds made up of water droplets (bright white) and underlying snow/ice (darker grey). ...

CIMSS produces Advanced Technology Microwave Sounder (ATMS) Lake Ice concentration images in a format that can be inserted into AWIPS.  These images are created from data downloaded (available at this ftp site;  imagery is also available here) at the DB antennae at CIMSS, and processed with MIRS algorithms (all MIRS products are available...
