GOES-East airmass RGB imagery, above, shows the evolution of a strong system that brought heavy rain to the central United States as well as snow over the western Great Lakes. The Potential Vorticity Anomaly that supported the surface cyclone, orange in the RGB shown above, starts over the Rocky Mountains and moves... 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...

MIMIC Total Precipitable Water fields for the 24 hours ending 1800 UTC on 21 October 2024, above, show a stream of rich moisture pulled northward into Alaska ahead of a strong storm over western Russia. The result was large snowfall rates over much of central and northern Alaska, as shown... Read More
VIIRS infrared imagery (I05 imagery at 11.45 µm) from the NOAA-21 (mislabeled, alas, at Suomi NPP) show high-resolution infrared imagery at about 90-minute time-steps. Cold Cloud tops associated with a low pressure system bringing light snow to northern Alaska are apparent — but during the gap from 00-08 UTC on... Read More
