GOES-17 ABI Band 7 Shortwave Infrared (3.9 \u00b5m) Imagery, 1737-2006 UTC on 13 March 2019 (Click to play mp4 animation)<\/p><\/div>\n

Very strong winds over the High Plains of Texas and New Mexico (associated with the extraordinary blizzard to the north<\/a>) helped quickly spread a Grass Fire that developed over north Texas, north of Amarillo. (Tweet from NWS Amarillo<\/a> is here<\/a>). GOES-17’s Mesoscale Sector 1 was over the southern Plains, and viewed the fire development in 1-minute increments. The shortwave infrared (3.9 \u00b5m) imagery is shown in an mp4 animation above (Click here<\/a> for an animated gif). Visible Imagery is shown below, and the smoke plume from the fire is difficult to see. (Click here<\/a> for an animated gif). The fire first became apparent in the shortwave infrared imagery around 1837 UTC.<\/p>\n

GOES-17 Fire Detection and Characterization Algorithm (FDCA) products (the Baseline Fire Product) are not yet available: distribution of these products has been delayed because of GOES-17’s Loop Heat Pipe problems (https:\/\/cimss.ssec.wisc.edu\/satellite-blog\/archives\/29874; Blog Post 2<\/a>). GOES-16 did view this fire, however, and are shown in the animation below. FDCA products are not produced for Mesoscale Domains, however, so only a CONUS product, available every 5 minutes is shown. The fire was first visually apparent in the Band 7 imagery at 1837 UTC (the fire is just northwest of a lake, and halfway between Stinett and Four Way on the map, and Fire Temperature was diagnosed starting at 1842 UTC. Note that the pixels from GOES-16, above the Equator at 75.2 Longitude are quite different from those from GOES-17, above the Equator at 137.2 W Longitude.<\/p>\n

Both GOES-17 (and GOES-16) 3.9 \u00b5m Imagery could be used to monitor this event. GOES-16 Baseline Fire Detection products also viewed the fire, but these products are not produced for Mesoscale domains so only a 5-minute cadence is available.<\/p>\n

Suomi NPP overflew the region after 2030 UTC on 13 March, and it provided a higher-resolution image of the fire than is available from GOES. The toggle below compares the shortwave infrared<\/a> (3.9 \u00b5m), the snow\/ice channel<\/a> (1.61 \u00b5m) and the visible<\/a> (0.64 \u00b5m) from VIIRS (the Visible Infrared Imaging Radiometer Suite). The shape of the fire is better defined in the VIIRS imagery. (A second fire is also apparent to the east). A useful strategy, if possible, is to use GOES-17 or GOES-16 to monitor the evolution of the storm, and to use VIIRS imagery from Suomi NPP and\/or NOAA-20 to see details in the horizontal structure. This animation<\/a> compares the fire views (at 2043 UTC) from Suomi NPP, GOES-16 and GOES-17.<\/p>\n
