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
