1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.3 µm) images (above) showed Lee as it intensified to become a Category 1 Hurricane in the Central Atlantic Ocean on 06 September 2023. The coldest cloud-top infrared brightness temperatures were around -90C (brighter white pixels embedded within darker black areas). Lee had... Read More

GOES-18 (GOES-West) SO2 RGB and Ash RGB images (above) showed the east-southeastward drift of a volcanic cloud produced by an explosive eruption of Mount Shishaldin that began shortly before 1600 UTC on 05 September 2023. The initial volcanic cloud exhibited pale shades of yellow in both RGB types, suggesting a mixture of SO2 and Ash; after 1900 UTC, the... Read More

5-minute GOES-16 (GOES-East) “Red” Visible (0.64 µm) + Fire Power derived product (a component of the GOES Fire Detection and Characterization Algorithm FDCA), Shortwave Infrared (3.9 µm), “Clean” Infrared Window (10.3 µm) and Fire Temperature RGB images (above) showed signatures of the Game Preserve Fire in northern Walker County, Texas late in the day on 01 September 2023. The wildfire forced... Read More

Overlapping 1-minute Mesoscale Domain Sectors provided 30-second GOES-16 (GOES-East) “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.3 µm) images (with/without an overlay of GLM Flash Extent Density) (above) — which included 15-minute plots of METAR surface reports and hourly plots of Fixed Buoy reports as Category 3 Hurricane Idalia made landfall along the Big Bend coat...
