New satellite imagery of California reveal not just the extent of its wildfire damage , but the depth of the loss .
The maps derived from the planet datum show how far two major fires spread as well as how badly each region burned . Darker color represent near - consummate release — charred landscape painting with little to no living botany depart . Lighter tan regions interpret areas where the flack was severe , but some Sir Herbert Beerbohm Tree and plants still survive .
The Operational Land Imager on Landsat 8 captured this image on Sept. 26, 2020, showing the extent of the wildfire damage.
The artificial satellite data was collected by Landsat 8 on Sept. 26 , during a absolved day after week of smoke that blanketed the Bay Area .
" We needed a clear sight of the land control surface to make these measurements , and we were lucky enough to get one after so many smoky day , " Christopher Potter , a removed - sensing investigator atNASA ’s Ames Research Center , told NASA ’s Earth Observatory . " It was the first planet image we could use to secern how severe the burn was across a across-the-board area . "
The imagination captured the CZU Lightning Complex ardor near Santa Cruz , and the SCU Lightning Complex flak in the Diablo Mountains . The CZU Lightning Complex ardour began on Aug. 16 , concord to Cal Fire , and burned for 37 day before being contain . The firing burn 86,509 acres ( 135 square international mile , or 350 hearty kilometers ) . The SCU Lightning Complex heat on Aug. 18 and burned 396,624 landed estate ( 619 satisfying miles , or 1,605 straight kilometers ) over the next 44 days , according to Cal Fire .
An outburst of dry lightning in August 2020 triggered wildfires across the state of California.

By comparingnear - infraredand shortwave - infrared wavelength data from Sept. 26 to the same data collected on July 24 , before the firing , Potter and his workfellow created a normalized tan ratio render how much vegetation was lost in each fire . The result maps show that the CZU Lightning Complex scar was burned deeply into the earth , belike go out little but charred tree soapbox , ash tree and soot behind . Most of the SCU Complex fire shows more surviving vegetation .
Green area on the function show a gain in flora , which is probably due to seasonal maturation or farming out of doors of fire scars .
According to the Earth Observatory , the CZU Lightning Complex fervor waste coastal wood full of tanoaks , Douglas firs andredwoods .
" It is raise up to see how much of the sequoia forest was burned , " Potter said .
The SCU Complex fire burned grassland and oak tree timber .
" It is rarified that we get more than one large lightning - induced fervidness in a year in California ; this class , we had 10 lightning complex attack , " Potter told the Earth Observatory . " Some researcher imagine these lightning storms may be related toclimate variety . Ifglobal warmingmeans more lightning storms like this in California , then we are in trouble . "
