1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Clean” Infrared Window (10.3 µm) + Total Precipitable Water (TPW) images (above) showed severe thunderstorms that developed along a cold front that moved north-northeast across Argentina and Uruguay on 01-02 December 2023. Pulses of thunderstorm overshooting tops occasionally exhibited infrared brightness temperatures in the -85 to -90ºC range (brighter white... Read More

10-minute interval GOES-16 (GOES-East) True Color RGB images (source) from 0930-1900 UTC on 13-26 November 2023 (above) showed Iceberg A23a just east-northeast of Joinville Island (at the tip of the Antarctic Peninsula). Although cloud-free periods were scarce during those 14 days, even on most of the cloudy days the silhouette... Read More

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) Day Cloud Phase Distinction RGB images with an overlay of GLM Flash Extent Density (above) showed a glaciating (brighter shades of green) to glaciated (pale shades of yellow) lake effect snow (LES) band streaming inland off Lake Erie on 17 November 2023. There were 4 brief periods of lightning activity seen just south of the Buffalo,... Read More
