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
10-minute Full Disk scan GOES-18 (GOES-West) Air Mass RGB images (above) showed a compact polar low as it migrated southeastward across the Bering Sea (not far south of the sea ice edge: surface analyses) on 27-28 January 2024. As the polar low moved through the Pribilof Islands on 28 January, St Paul Island (PASN)... 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
Target Sector (2.5-minute interval) JMA Himawari-9 AHI Red Visible (0.64 µm) and Clean Infrared Window (10.4 µm) images (above) showed Invest 90P as it intensified to become Tropical Cyclone Kirrily over the Coral Sea on 23-24 January 2024. Visible images showed multiple exposed low-level circulation centers, while Infrared images showed that deep convection was mainly developing west... Read More
