This short tutorial will explain how Polar2Grid can show individual isobaric levels, and also lapse rates (dT/dp) between two isobaric levels. Polar2Grid is CSPP software designed to process files either from the NOAA NODD (EDR files for NOAA-20 are here; EDR files for NOAA-21 are here) or from Direct Broadcast antenna... Read More

Fog and Low Clouds are an important hazard with respect to air and surface travel. How can these obstructions to visibility be highlighted from satellite? The toggle above shows the Night Fog Brightness Temperature Difference and the Night Microphysics RGB, popular satellite products to detect regions of fog. Blue regions... Read More

Cold air over the Great Lakes (see the plot of 850-mb temperature from RAOB stations at 1200 UTC below; note the similarity in temperatures and wind speeds over the Great Lakes states) means Lake Effect Snow. The animation above (source) shows snow bands over western lower Michigan and also downwind... Read More

GOES-West imagery centered over the Samoan Islands, shown above in an animation, shows a region of rich moisture surrounding those islands (purple in the enhancement, which suggests values or 2-2.2″), but the islands themselves are within a dry pocket (TPW values closer to 1.7″, orange/rust in the enhancement used). Total... Read More
