Fuel consumption is a critical component for estimating the effectiveness of prescribed fire for reducing fuels, emissions, and other fire effects. Because little research on wildland fuel consumption has been conducted in the eastern United States, there are few reliable validation datasets to assess the sensitivity, biases, and uncertainties of currently used fuel consumption models. The data collected from the 29 units were used to test Consume and the First Order Fire Effects Models (FOFEM), two currently available fuel consumption prediction systems. Airborne infrared mapping and associated ground measurements were performed, and a new calibration approach allows us to use data from a single bandpass infrared detector to estimate total fire power. With the new calibration, we are able to map fire heat release and fuel consumption for comparison with Consume and FOFEM.
