A series of LightningCast Probability plots from this RealEarth-powered website, below, shows increasing probabilities of lightning over the South Pacific to the south of American Samoa’s Manu’a Islands. The 75% contour (magenta) appears at 0530 UTC; the first GLM observation is shown at 0620 UTC. LightningCast is the probability that a GLM observation will occur... Read More

10-minute Full Disk GOES-16 (GOES-East) “Red” Visible (0.64 µm), Shortwave Infrared (3.9 µm) and “Clean” Infrared Window (10.3 µm) images (above) showed that a wildfire complex in southern Brazil produced a series of 4-5 pyrocumulonimbus (pyroCb) clouds on 13 November 2023. The coldest pyroCb cloud-top 10.3 µm brightness temperature was -74.4ºC at 1530 UTC.Regarding the wildfire... Read More

CIMSS provides (free of charge) CSPPGeo software that can create (and plot) gridded GLM data from GLM Level 2 LCFA files. The data from those files can then be plotted by geo2grid on top of ABI data to give an idea of how much lightning is occurring each minute. On... Read More

1-minute Mesoscale Domain Sector GOES-18 (GOES-West) “Clean” Infrared Window (10.3 µm) images (above) showed Hurricane Otis as it approached the coast of Mexico, making landfall near Acapulco (Acapulco International Airport, METAR identifier MMAA, is located about 16 miles southeast of the city center) around 0625 UTC on 25 October 2023. During the 11-hour time period shown,... Read More
