Himawari-9 imagery for the hour surrounding an RCM-1 pass over the center of Severe Tropical Cyclone Herman, below, shows strong convection (with widespread brightness temperatures colder than -85oC — light purple in this enhancement — with isolated pixel values cooler than -90oC — in purple). Peak Synthetic Aperture Radar (SAR)... Read More

GOES-16 (GOES-East) Shortwave Infrared (3.9 µm), Night Fog BTD (10.3 µm – 3.9 µm) and Nighttime Microphysics RGB images (above) displayed the thermal signature — via a single warm pixel — of a fire that resulted from a BNSF train derailment (media report) in Raymond, Minnesota at 0602 UTC (1:02 AM CDT) on 30 March 2023.  Although the...

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) Mid-level Water Vapor (6.9 µm) images (above) include an overlay of GLM Flash Extent Density — and showed the distinct circulation of a middle-tropospheric closed low (400 hPa analysis) as it moved northeastward across Illinois and Indiana into southern Lower Michigan on 25 March 2023. Isolated clusters of brief lightning activity were... Read More
