DIXIE FIRE MAP 2021 UPDATE

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. The fire tracking data identify periods of rapid fire expansion and active fire detections within the perimeter from continued flaming and smoldering behind the active fire fronts. This approach provides a detailed perspective on the behavior of the Caldor fire, just the second fire in California history to cross the Sierra Nevada Mountains. Yellow lines indicate the new fire fronts from active fire data (red points) every 12 hours.

Every 12 hours, the fire tracking algorithm uses new active fire detections to update the total fire perimeter and estimate the position of active fire lines where the fire may continue to spread. This visualization highlights data from a new 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 graph shows the cumulative burned area in square kilometers. The red points show the location of active fire detections, while the grey region shows the estimated total area burned. The yellow outlines track the position of the active fire lines for the last 60 hours, with the latest location of the fire front in the brightest shade of yellow. This visualization shows the spread of the Caldor fire between August 15 and October 6, 2021, updated every 12 hours based on new satellite active fire detections.
