KNP Complex and Windy Fires in California

Image captured on Oct 3, 2021, by the MODIS instrument aboard the Aqua satellite.

MODIS data image with thermal anomalies of KNP Complex and Windy Fires, California.


True-color corrected reflectance image of the KNP Complex and Windy Fires in California. This image was acquired by Moderate Resolution Imaging Spectroradometer (MODIS), aboard the Aqua satellite. This image is a true-color Red-Green-Blue (RGB) composite where Red is Band 1, Green is Band 4, and Blue is Band 3. These images are called true-color or natural color because this combination of wavelengths is similar to what the human eye would see. The images are natural-looking images of land surface, oceanic and atmospheric features. Overlaid on the image are the Aqua/MODIS Fires and Thermal Anomalies layer which is shown as orange dots, these represent the center of a 1km pixel containing one or more fires.

The KNP Complex and Windy Fires are in the lower right with smoke from these fires covering the Central Valley. The KNP Complex Fire is impacting the Sequoia and Kings Canyon National Parks as well as residences and infrastructure in the region. The Windy Fire is also affecting several communities where many structures and infrastructure are threatened. Use the back and forward arrows in the lower left corner of the map to see when the fires began to be visible in the satellite imagery.
