Poomacha Fire, San Diego County, CA
13:09 PDT 27 October 2007

As viewed by the FireMapper™ Thermal-Imaging Radiometer

Difficult flying conditions today with low clouds made data collection spotty.
There may be gaps in the firelines due to missing data. The primary fire areas were covered.

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 cooling ash but could be associated with bare ground away from fire.
