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...

The 1200 UTC sounding from Hilo HI (91285) was unavailable on 29 October 2024. (Here is the sounding from 0000 UTC). When such a failure happens, there is a backup: NUCAPS profiles show thermodynamic information that is retrieved from infrared and microwave information on NOAA-20, NOAA-21 and MetopC satellites, and...

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
