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
