GOES-17 (GOES-West) True Color RGB images created using Geo2Grid (above) showed the diurnal variation of smoke from the Dixie Fire, Beckwourth Complex, Caldor Fire and Tamarack Fire in Northern California on 25 August 2021. Early in the day, smoke from the previous day of fire activity that had settled into valleys was evident — but as daytime... Read More
Synthetic Aperture Radar (SAR) winds over the northwest Pacific, above, derived from Radar Constellation Mission (RCM) Satellite #2, shows a narrow ribbon of strong winds (>30 knots) stretching from 50 N, 138 W towards 53 N, 140 W. What kind of cloud imagery is associated with this wind feature?Near-sunrise visible... Read More
GOES-16 (GOES-East) Shortwave Infrared (3.9 µm) images (above) showed rapid growth of the thermal anomaly — cluster of hot pixels, red enhancement — associated with the Greenwood Fire in northeast Minnesota on 23 August 2021. With gusty winds in the wake of a frontal passage, the fire exhibited extreme behavior on this day, growing... Read More
GOES-16 (GOES-East) Night Fog BTD (10.3-3.9 µm) and “Red” Visible (0.64 µm) images on 23 August 2021 (above) showed the nighttime formation of widespread river valley fog across parts of the Mid-South and adjacent Appalachians — followed by morning fog dissipation once solar heating initiated boundary layer mixing. With surface high pressure in... Read More
