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. This approach provides a detailed perspective on the behavior of the Caldor and Dixie fires, identifying periods of rapid fire expansion and active fire detections within the perimeter from continued flaming and smoldering behind the active fire fronts.
