Deadly fires on the island of Maui occurred in an environment favorable to fire development: dry and windy. What kind of satellite data could be used to assess those conditions? Sentinel-1A overflew the western Hawai’ian islands near sunset on 8 August 2023 (that is, at 0440 UTC on 9 August), as shown above. Widespread 30-knot winds... Read More

GOES-18 (GOES-West) Day Land Cloud Fire RGB, Shortwave Infrared (3.9 µm), “Clean” Infrared Window (10.3 µm) and “Red” Visible (0.64 µm) images with an overlay of the Fire Power derived product — Fire Power is a component of the GOES Fire Detection and Characterization Algorithm FDCA — (above) showed signatures associated with a wildfire (located about 20 miles WNW of Mayo,...
