With GOES-15 Routine Scan mode “SUB-CONUS” sectors, images were available up to 6 times per hour (at :00, :11, :15, :30, :41, and :45);<\/em> with GOES-13 in Rapid Scan Operations (RSO) mode, images were available up to 8 times per hour (at :00, :07, :15, :25, :30, :37, :45, and :55)<\/em>. The GOES-14 satellite had been placed into Super Rapid Scan Operations for GOES-R (SRSO-R<\/strong><\/a>) mode, providing images at 1-minute intervals to emulate what will be available with mesoscale sectors from the ABI instrument<\/strong><\/a> on GOES-R<\/strong><\/a>.<\/p>\n

For the central Montana wildfire, the first unambiguous signature of a darker black wildfire hot spot began to appear on each satellite after about 1945 UTC, with the first color-enhanced pixels (signifying a shortwave IR brightness temperature of 331.9 K) showing up on the 2026 UTC GOES-14 image. The hottest fire pixel\u00a0 on the GOES-15 images was 336.5 K<\/strong> at 2130 UTC, while the hottest fire pixel on GOES-13 images was 329.8 K<\/strong> at 2125 UTC. From 2120 to 2130 UTC, the hottest GOES-14 fire pixels were 341.2 K<\/strong> (the saturation temperature of the 3.9 \u00b5m detectors on that satellite).<\/p>\n

With the finer spatial resolution of the shortwave IR detectors on the polar-orbiting MODIS (1-km) and VIIRS (375-meter) instruments, a fire hot spot was first detected on the 1857 UTC VIIRS image (below)<\/strong><\/em>.<\/p>\n
