![]() ![]() 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. Click on aircraft icons to see details.Following an unprecedented outburst of dry lightning in August 2020, wildfires ignited across the state of California. Flightradar24 (Shows aircraft, including some firefighting fixed wing and helicopters, but not all.Move your cursor to see estimated wind direction and speed at that spot.) Zoom Earth (Shows wildfires and wind speed and direction, and disclaims accuracy.To return to see all cameras you are interested in click on "Camera Management." To learn how to use all features on the ALERT California website, watch its Tutorial Video. To find cameras for your area of interest, zoom in on the map to include only the icons for cameras you are interested in seeing views from, then to see views from a specific camera click on its icon on the map then click on the hyperlink in the label that pops up, or, click on the image from the camera on the right. ALERT California shows you real time views from wildfire cameras.Other websites that can help you understand wildfire conditions like wind direction and speed, and to some degree the air support working on suppression, are (note, some disclaim accuracy): InciWeb California Fire Incidents web page (Focus is on fires on Federal land.).CAL FIRE's Current Fire Information web page(Active fires have a red icon, old fires gray.).Some inaccuracies, but very helpful information.) Dots/detections older than 48 hours are removed from the map. Satellite heat-detection-dot colors mean: red = within last 12 hours, orange = within 12 to 24 hours, yellow = 24 to 48 hours.
