The Dixie wildfire, the northern most of the two, was the largest fire in California history with a total area (1,505 sq. miles) just above the size of U.S. state Rhode Island (1,214 sq. miles). In total, the Dixie fire burned for more than 100 days and this map displays the total extent between July 14 and October 22, 2021. The Caldor wildfire, east of Sacramento, is the second fire in California history to cross the Sierra Nevada Mountains. In total, the Caldor fire burned for more than 80 days through the El Dorado National Forest, threatening the communities of Meyers and South Lake Tahoe.

Datasets used in this visualization
SRTM DEM (Collected with the SIR-C sensor)
Suomi-NPP Fire Events Data Suite (FEDS) GeoPackage (A.K.A. Fire Events Data Suite (FEDS) GeoPackage) (Collected with the VIIRS sensor)
The authors used the Suomi-NPP VIIRS I-band fire location data product (VNP14IMGML, Collection 1 Version 4), the U.S. National Land Cover Database (NLCD 2016) and gridMET product27 dead fuel moisture to develop an automatic system to dynamically track the growth of all fire events at a regional scale.
