The Dixie Fire (which had grown to become the largest on record for the state of California) began burning on 13 July 2021 — and on 13 August 2021, Shortwave Infrared (3.9 µm) images from 1-minute GOES-17, 15 to 30-minute GOES-15, 15-to 30-minute GOES-14 and 5-minute GOES-16 (above) showed the thermal signature (darker red to black pixels) during the 1200 UTC – 1801 UTC period. The images were displayed in the native projection of each satellite.

Although there was smoke and some clouds across the area at the time of the Suomi NPP overpass, the VIIRS False Color RGB image provided a good view of most of the fire’s large burn scar (shades of red to brown). On this day, the fire had burned nearly 518,000 acres, and was 31% contained.
