Image 1: Thermal Mosaic
Plan view of fire. Warmer tones represent recent or active combustion; areas of light gray are cooling ash or warm bare ground and the low temperatures of unburned forest and cool ground are shown in darker gray (see chart above).

Purple is used to show very warm ground that may or may not be fire-related. Purple pixels immediately adjacent to red pixels can be interpreted to be cooling ash; purple pixels far from any red pixels may be interpreted as solar heating on bare rock.
