GOES-17 (GOES-West) True Color RGB images created using Geo2Grid (above) showed the diurnal variation of smoke from the Dixie Fire and the Caldor Fire in Northern California on 30 August 2021. Early in the day, smoke from the previous day of fire activity that had settled into valleys was apparent — however, as daytime heating continued this valley smoke was ventilated... Read More
The animation above, of GOES-16 Visible (0.64 µm) imagery, shows Tropical Storm Kate at sunrise with convection near the storm center and to its east. (An overnight image from Suomi NPP’s Day Night Band, below, taken from NASA Worldview, also shows convection near the storm center.) As the day progresses, however,... Read More
Day Night Band imagery from the VIIRS (Visible Infrared Imaging Radio-Spectrometer) instrument on Suomi NPP and NOAA-20 allows satellite-borne estimates of power outages after strong storms. The imagery from Suomi NPP (0740 UTC) and NOAA-20 (0830 UTC) (orbital paths can be viewed here) shows a sharp reduction in the amount... Read More
