Spread of the Dixie Fire

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. 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. Yellow lines indicate the new fire fronts from active fire data (red points) every 12 hours. This approach provides a detailed perspective on the behavior of the Dixie fire, the largest fire in California history. The fire tracking data identify periods of rapid fire expansion, spot fires from blowing embers outside of the large fire perimeter, and active fire detections within the perimeter from continued flaming and smoldering behind the active fire fronts. In total, the Dixie fire burned for more than 100 days, including more than a month of fire activity after the perimeter was contained in mid-September.
