A sequence of Suomi-NPP VIIRS Infrared Window (11.45 µm) images (above) displayed the development of a coma-shaped cloud structure associated with a low pressure system near the North Pole (northwest of Greenland) on 13 February 2024. The single METAR surface report plotted is Svalbard, Norway (the reports for CWLT —... Read More
GOES-18 (GOES-West) Day Land Cloud Fire RGB, Shortwave Infrared (3.9 µm), “Clean” Infrared Window (10.3 µm) and “Red” Visible (0.64 µm) images with an overlay of the Fire Power derived product — Fire Power is a component of the GOES Fire Detection and Characterization Algorithm FDCA — (above) showed signatures associated with a wildfire (located about 20 miles WNW of Mayo,...
