A new PC-based Visual Basic software program called FEPS version 1.0 (Fire Emission Production Simulator) is now available on the Web. It is a user-friendly computer program, designed to predict emissions and heat release characteristics from prescribed or wildfires using system defaults, user templates, specific event information or conjectural input at any spatial scale or level of specificity. Algorithms are included to predict fuel consumption that partitions outputs among flaming, smoldering and residual combustion stages based on fuel moisture inputs. Approximate plume rise is also predicted by FEPS.
