FOFEM 5.0 (First Order Fire Effects Model) is a computer program that was developed to meet needs of resource managers, planners, and analysts in predicting and planning for fire effects. FOFEM predicts tree mortality from surface fire, based on flame length or scorch height, and tree species and size. It predicts consumption of down woody fuels by size class, and the resultant fire intensity over time using the BURNUP model. It predicts emissions (and emission rate) of PM10, PM2.5, CO, CO2, CH4, NOX and SO2 by flaming and smoldering combustion. It predicts soil heating at a range of soil depths over time since ignition.
