5-minute GOES-16 (GOES-East) “Red” Visible (0.64 µm), Shortwave Infrared (3.9 µm), Fire Power derived product and Fire Temperature RGB images (above) displayed signatures of the wind-driven “Turkey Day” grassland fire in Oglala Lakota County in southwestern South Dakota on 23 November 2022. Peak 3.9 µm infrared brightness temperature (102.53ºC) and Fire Power (1570.84 MW) values were... Read More

The animation of GOES-17 visible imagery (Band 2, 0.64 µm), above, (created at the CSPP Geosphere site) shows the characteristic signal of Sun Glint — the moving bright region. Sun glint (also discussed on this blog here, here, here, here and — for moonglint: here!) occurs when radiation from the Sun reflects... Read More
