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 Super Typhoon Man-Yi as it made landfall along the Philippines island of Luzon on 17 November 2024. Low-altitude mesovortices were apparent within the eye as it was offshore — then a notable convective burst developed as the... Read More
Day Night Band imagery from the three JPSS Satellites — NOAA-21 (1515 UTC), Suomi NPP (1537 UTC) and NOAA-20 (1602 UTC) show Tropical Storm Man-Yi as it approached the southern Marianas Islands early in the morning on 13 November 2024 (Guam Time). These images were created using CSPP Software and data... Read More
The Community Satellite Processing Package (CSPP) software Polar2Grid supports the creation of imagery using Microwave Integrated Retrieval Software (MIRS) algorithms. This is useful because on-line sources of imagery occasionally go missing. Consider, for example, the Snowfall Rate values that are available at this site from GINA. NOAA-20 was viewing parts of...

GOES-18 Airmass RGB imagery, above, from 1500-1820 UTC on 28 October, show light snow over much of central Alaska as a storm system moves into the state. Temperatures at 500 mb, below, derived from NUCAPS profiles (as shown in the toggle), show a tongue of warmer air positioned with the cloud feature (shown as white) in... Read More
