FOFEM 5.2 is a simple, yet versatile computer program that predicts first order fire effects using text and graphic outputs. It can be used in a variety of situations including: determining acceptable upper and lower fuel moistures for conducting prescribed burns, determining the number of acres that may be burned on a given day without exceeding particulate emission limits; comparing predicted fuels reduction for alternative prescribed burn scenarios; and predicting the effects of wildland fire. This fact sheet describes what inputs are needed to run FOFEM, the outputs that are produced, and how to download a copy from the internet.
