WebThe emission factor database has been integrated into the most recent version of the First Order Fire Effects Model (FOFEM). Our scientists are developing more accurate forecasts of fire and smoke conditions to protect public and firefighter health as part of our Fire and Smoke Model Evaluation Experiment (FASMEE). WebPredictive accuracy of all models was compared to the accuracy of the general, non-species specific mortality model used in the First Order Fire Effects Model (FOFEM) prior to version 5.7. The new species-specific models improved prediction of fire-caused tree mortality by 0 % to 48 %.
