Dixie and Caldor Wildfires Locator Maps - 2021

This map illustrates perimeter data for two California wildfires and allows for the comparison of their size and position. The data is derived from a new automatic fire detection and tracking approach (Chen et al., 2022) based on near-real time active fire detections from the VIIRS sensor on the Suomi-NPP satellite. The tracking system’s algorithm uses new active fire detections to update the total fire perimeter and estimate the position of active fire lines every 12 hours.

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.
