The image shows the spread of the fire between 19 August and 2 September, 2013, as reported by fire managers on InciWeb. Each day in the period is represented by a different color, and the difference from one day to the next shows how much the fire burned that day.

The fire was extremely active on some days and less active on others, depending largely on weather conditions. For example, much of the burning in Yosemite National Park occurred on August 26, when crews reported extreme fire behavior. The fire extent is overlaid on a topographic map to illustrate just how challenging the terrain has been for firefighters. The Rim Fire is burning in a mountainous, difficult-to-access area, making aerial support essential for managing the fire.
The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASAs Terra satellite captured this false-color image of the Rim fire burning in and near Yosemite National Park on August 30, 2013. The image, based on ASTERs observations of visible and infrared light, highlights the contrast between burned and unburned vegetation. Unburned vegetation appears bright red, whereas burned areas are gray. Thick plumes of smoke are also visible billowing from the fire. Source: NASA Earth Observatory

The Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite tracked the growth of the Rim Fire between 23 and 26 August. The VIIRS day-night band is extremely sensitive to low light, making it possible to see the fire front from space at night. The brightest, most intense parts of the fire glow white, exceeding the brightness of the lights of Reno, Nevada, to the north. Pale gray smoke streams away from the fire, generally to the north.
