It is based on the ISI and the BUI, and is used as a general index of The system consists of six components: three primary subindexes representing fuel moisture, two intermediate subindexes representing rate of spread and fuel consumption, and a final index representing fire intensity as energy output rate per unit length of fire front. 1997) are used with the Canadian Forest Fire Weather Index … The purpose of the FWI System is to account for the effects of weather on forest fuels and forest fires. It also includes equations for computing % moisture content from the Duff Moisture Code (DMC) and a batch csv calculator for FWI.
