Thermal signatures of the Chevron El Segundo refinery fire near Los Angeles
5-minute GOES-18 Near-Infrared (0.87 µm, 1.61 µm and 2.25 µm) and Shortwave Infrared (3.9 µm) images, from 0416-0701 UTC on 03 October; Interstate highways are plotted in red [click to play MP4 animation]
In contrast, GOES-18 Microphysics RGB images with an overlay of Next Generation Fire System (NGFS) Fire Detection polygons (below) exhibited a distinct thermal signature for a significantly longer time period (ending at 1626 UTC).
