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.
CAL FIRE MAP OF DIXIE FIRE UPDATE
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 dropdown menu offers multiple resolutions for a 16:9 aspect ratio. Perimeter of the Caldor wildfire as of October 6, 2021. This image shows the spread of the Caldor fire between August 15 and October 6, 2021, with the fire line for each 12-hour time step shown in a different color. 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 image shows the extent of the Caldor fire on August 28, 2021.
This image shows the extent of the Caldor fire on August 21, 2021.
CAL FIRE MAP OF DIXIE FIRE MOVIE
This movie is identical to the above movie except that it is played twice the speed. The graph shows the cumulative burned area in square kilometers.Coming soon to our YouTube channel. 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. 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 Caldor wildfire, east of Sacramento, is the second fire in California history to cross the Sierra Nevada Mountains. 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 Dixie wildfire, the northern most of the two, was the largest fire in California history with a total area (1,505 sq.
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 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. This map illustrates perimeter data for two California wildfires and allows for the comparison of their size and position.
