Service Description: The Probability of Canopy Fire dataset is the sum of the proportion of fires for the percentile weather categories where the predicted fire type is passive or active. Fire Type is a fire behavior output generated during the calculation of the Fire Threat Index (FTI). Fire type categorizes the fire by mode of propagation - surface fires and crown fires. Crown fires have further been classified as either passive or active. Surface fires are defined as a fire that spreads through surface fuel without consuming any overlying canopy fuel. Surface fuels include grass, timber litter, shrub/brush, slash and other dead or live vegetation within about 6 feet of the ground. Passive crown fires are defined as a type of crown fire in which the crowns of individual trees or small groups of trees burn, but solid flaming in the canopy cannot be maintained except for short periods. Active crown fires are defined as a type of crown fire in which the entire fuel complex (canopy) is involved in flame, but the crowning phase remains dependent on heat released from surface fuel for continued spread. Fire behavior outputs are influenced by three environmental factors - fuels, weather, and topography. Weather is by far the most dynamic variable as it changes frequently. To account for this variability, four weather percentiles categories were created from historical weather observations to represent low, moderate, high, and extreme weather days for each weather influence zone. A weather influence zone is an area where, for analysis purposes, the weather on any given day is considered uniform. Fire behavior outputs (fire type, rate of spread, and flame length) are computed for each of these percentile weather categories in order to determine potential fire behavior under different weather scenarios.
