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
