Suomi NPP VIIRS Day/Night Band (0.7 µm) and Near-Infrared (1.61 µm and 2.25 µm) images along with the VIIRS Active Fires product (credit: William Straka, CIMSS) [click to enlarge]

A comparison of Suomi NPP VIIRS Day/Night Band (0.7 µm) and Near-Infrared (1.61 µm and 2.25 µm) images along with the VIIRS Active Fires product (above) showed nighttime visible reflectance and thermal signatures of the many wildfires burning across Northern California at 1001 UTC or 3:01am PDT on 20 August 2020. A closer view is available here.

1-minute Mesoscale Domain Sector GOES-17 (GOES-West) Fire Temperature Red-Green-Blue (RGB) and “Red” Visible (0.64 µm) images (below) displayed the thermal signatures and smoke plumes associated with the Northern California fires.
