Such imagery can help land- and forest managers and other agencies as they assess areas with the worst damage and start cleanup. ![]() “It was the first satellite image we could use to tell how severe the burn was across a broad area.” “We needed a clear view of the land surface to make these measurements, and we were lucky enough to get one after so many smoky days,” said Potter, who specializes in satellite studies of land-cover change. The image below shows the same areas on September 26 as observed in natural color by the Operational Land Imager (OLI) on Landsat 8. ![]() Beyond the fire burn scars, green and light brown areas likely indicate crop growth and harvesting or seasonal changes in trees and other vegetation. Tan areas were significantly burned but still have some live vegetation. Areas colored dark brown have little to no live vegetation left the landscape is mostly covered in soot, ash, and charred stumps and stems. Shades of tan and brown reveal the severity of the burns from each fire, with the darkest shades revealing the greatest damage to the landscape. The data were analyzed by remote sensing scientist Christopher Potter and colleagues at NASA’s Ames Research Center. The technique, known as a normalized burn ratio, uses near-infrared and shortwave-infrared data collected on July 24 and September 26, 2020, to detect changes in the greenness of the landscape. The map above uses Landsat 8 satellite data to provide some measure of the severity of the burns from the SCU and CZU Lightning Complex fires of August and September 2020. Now state and federal agencies are working to assess the damage. Raging for weeks to months amid heat waves and dry weather, the fires charred millions of acres and consumed homes, livelihoods, and lives. Klamath National Forest sprawls over more than 2,650 square miles (6,863 square kilometers) in Northern California and southern Oregon.Ī slew of other lightning-caused fires were reported Tuesday in Northern California, including in Mendocino County, Shasta-Trinity National Forest and the Tahoe area, although most were small and quickly contained, fire officials said.Following an unprecedented outburst of dry lightning in August 2020, wildfires ignited across the state of California. That pattern was expected to break down on Thursday, with cooler and calmer weather entering the weekend. Their bodies were found inside a charred vehicle in the driveway of a home.įorecasters said weather would continue to be hot and dry but with instability caused by moist air being pulled into the region, bringing the threat of afternoon and evening dry thunderstorms with strong outflow winds. ![]() It reduced much of Klamath River, a scenic community of about 200 people, to ash and killed four people, including two who may have been trying to flee the flames. That fire started in the Klamath National Forest and exploded in size when a thunderstorm created winds up to 50 mph (80 kph). The Head Fire was burning near the site of the McKinney Fire, which began on July 29 of last year.
