The maximum 3.9 \u00b5m brightness temperature sensed was 138.7\u00baC \u2014 which is the saturation temperature for those ABI<\/strong><\/a> detectors. The fire prompted evacuation orders in the Topanga, California area.<\/p>\n A time-matched comparison of Shortwave Infrared images from Suomi NPP VIIRS (3.74 \u00b5m) and GOES-17 ABI (3.9 \u00b5m) at 0918 UTC or 2:18 am PDT is shown below (overpass times<\/strong><\/a> of the Suomi NPP satellite). Although a decrease in the fire’s intensity occurred during the subsequent overnight hours, the Shortwave Infrared brightness temperatures sensed by Suomi NPP and GOES-17 at that time were 59.9\u00baC and 28.1\u00baC, respectively.<\/p>\n Shortwave Infrared images from Suomi NPP VIIRS (3.74 \u00b5m)<\/em> and GOES-17 ABI (3.9 \u00b5m)<\/em> at 0918 UTC [click to enlarge]<\/p><\/div>1-minute GOES-17 True Color RGB images created using Geo2Grid<\/strong><\/a>\u00a0(below)<\/strong><\/em> revealed a series of \u201cpyrocumulus jump\u201d events (beginning around 01 UTC), when smoke\/cloud material was ejected to higher altitudes than the primary smoke plume.<\/p>\n<\/a>
