Here are three burn scars we analyized for Landsat TM radiant temperature:

We found the radiant temperature of burn scars to be significantly higher and more variable than the area within 10-km surrounding each burn scar:

Why are the burn scars significantly higher in radiant temperature?
Perhaps this is due to low transpirational cooling relative to the vegetated surrounding unburned areas?
