An animation of Topography + GOES-17 (GOES-West) “Clean” Infrared Window (10.35 µm) images (above) showed a southward-moving band of clouds responsible for producing heavy rainfall across portions of Interior Alaska on 02 August 2020. Cloud-top infrared brightness temperatures were as cold as -58ºC (brighter shades of yellow).GOES-17 “Red” Visible (0.64 µm) images... Read More
JMA Himawari-8 Ash Red-Green-Blue (RGB) images created using Geo2Grid (above) displayed the nearly continuous volcanic cloud emanating from Nishinoshima during the 1-week 25 July to 01 August period (faster animations are also available: gif | mp4).
