One of the gases emitted from the Mauna Loa eruption is SO2. The 0223 UTC 30 November update from this site notes that emission rates of approximately 250,000 tonnes [sic] per day were measured on 28 November! What satellite products can be used to diagnose this gas qualitatively and quantitatively? There is... Read More
GOES-16 (GOES-East) Mid-level Water Vapor (6.9 µm) images (above) showed the circulation associated with an anomalously-deep middle tropospheric cutoff low as it moved from northern Mexico across Texas during the 1301 UTC on 25 November to 2101 UTC on 26 November 2022 time period. Elevated convective elements rotating within the cutoff low helped to... 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
1-minute Mesoscale Domain Sector GOES-16 “Clean” Infrared Window (10.3 µm) images (above) include an overlay of GLM Flash Extent Density — which showed rapidly-cooling cloud-top infrared brightness temperatures (and intermittent lightning) over the eastern half of Lake Erie, associated with the initial impulse of lake effect snow (LES) immediately downwind of the lake...
