Description: This dataset is a 30-m cell size (downscaled from 120-m) raster representing annual burn probability across the project area. The individual-FOA BPs were integrated into this overall result for the project area using a natural-weighting method that Pyrologix developed on an earlier project and subsequently published (Thompson and others 2013; “Assessing Watershed-Wildfire Risks on National Forest System Lands in the Rocky Mountain Region of the United States”). With this method, BP values for pixels well within the boundary of a FOA are influenced only by that FOA. Near the border with another FOA the results are influenced by that adjacent FOA. The weighting of each FOA is in proportion to its contribution to the overall BP at each pixel.

Description: This dataset is a 30-m cell size (downscaled from 120-m) raster representing the mean conditional flame length (given that a fire occurs). It is a measure of the central tendency of flame length. This raster was calculated as the sum-product of iFLP_FILx and the midpoint flame length of each of the six iFLP_FILs. For iFLP_FIL6, for which there is no midpoint, we used a surrogate flame length of 20 feet in grass, grass/shrub, and shrub fuel, and in timber understory, timber litter, and slash we used 100 feet as the midpoint (representing torching trees).
