On 13 August 2020, Visible images from GOES-17 (GOES-West, positioned at 137.2ºW), GOES-15 (GOES-West backup, positioned at 128ºW), GOES-14 (on-orbit spare, positioned at 104.5ºW) and GOES-16 (GOES-East, positioned at 75.2ºW) (above) showed the morning dispersion of smoke from the Red Salmon Complex that had been burning in northern California. The images are displayed in the native projection of each satellite.

In southern California, Shortwave Infrared images from all 4 satellites (below) displayed thermal signatures (dark black to red pixels) from wildfires burning near Los Angeles. 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  — where extremely hot temperatures get displayed as cold (white).

GOES-15 was providing supplemental operations for GOES-17 during a period of maximum ABI Loop Heat Pipe thermal anomaly; GOES-14 had been brought out of storage for its annual 10-day test checkout.

The raw GOES data was acquired and processed by SSEC Satellite Data Services.
