The 10th and final special RADARSAT-2 data collection of SAR winds over the Guam Area of Responsibility (AOR) occurred on 24 November, and is shown above in a toggle with the Himawari-8 Clean Window imagery at the same time (Here is the same toggle as above but with SAR data... Read More

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

As an anomalously-strong upper-tropospheric jet streak was moving across the Mid-Atlantic region on 20 November 2022, GOES-16 (GOES-East) Upper-level Water Vapor (6.2 µm) images (above) displayed numerous 6.2 µm Derived Motion Wind (DMW) vectors having speeds of 190 knots and higher — with the jet streak axis passing just to the north of the Wallops,...
