CSPP software processes signals at Direct Broadcast antenna sites to create products and imagery with very low latency from Low-Earth Orbit (LEO) satellites. The software includes Microwave Integrated Retrieval System (MIRS) algorithms, including rain rate (available here). How well does that product do in capturing observed precipitation? The toggle above shows... Read More

The Direct Broadcast antenna at the UW-Madison CIMSS can receive information over much of the contiguous United States. This includes the NOAA-20 overpass that acquired data around 0910 UTC over southern California during a frontal passage. NOAA-20 supports both the Visible Infrared Imaging Radiometer Suite (VIIRS) and the Advanced Technology Microwave Sounder... Read More

The Night Microphysics RGB animation below, taken from the CSPP Geosphere website (direct link to animation) shows strong convection over the central Gulf of Mexico along with cloud conditions in the surrounding states. Note, for example, the expanding region of low clouds over Texas. The annotated images below (0216, 0646 and 1046 UTC) highlight... Read More

A toggle between NOAA-20 VIIRS Day/Night Band and Infrared Window images valid at 0827 UTC (2:27 AM local time) on 22 January 2024 (above) showed an opening of the Kivalliq Polynya along the northwest coast of Hudson Bay — which was the result of a period of strong offshore winds (Arviat Airport CYEK observations),...
