Thermal signatures varied between the 4 satellites, based upon differences in spatial resolution, viewing angle, and intermittent fire thermal signal attenuation by high clouds moving over the area. In the GOES-15 images, the occasional appearance of white pixels was due to a “roll-over” issue\u00a0 — where extremely hot temperatures get displayed as cold (white).<\/p>\n From left to right, GOES-17, GOES-15, GOES-14 and GOES-16 Shortwave Infrared images [click to play animation | MP4<\/strong><\/a>]<\/p><\/div>GOES-15 was providing supplemental operations for GOES-17 during a period of maximum ABI Loop Heat Pipe thermal anomaly<\/strong><\/a>; GOES-14 had been brought out of storage for its annual 10-day test checkout.<\/p>\n<\/a>
