This spatial dataset was produced with the Wildfire Exposure Simulation Tool (WildEST), a cloud-based geospatial fire behavior characteristic simulation system. WildEST performs multiple deterministic simulations under a range of weather types (wind speed, wind direction, fuel moisture content) and weights those results based on weather type probabilities (WTP).
This conditional risk to potential structures (cRPS) dataset represents the potential consequences of fire to a home at a given location, if a fire occurs there and if a home were located there. It is a measure that integrates wildfire intensity with generalized consequences to a home on every pixel, but does not account for the actual probability of fire occurrence.
The response function characterizing potential consequences to an exposed structure was applied to all burnable fuel types on the landscape regardless of whether an actual structure is present or not. The response function does not consider building materials of structures and is meant as an measure of the effect of fire intensity on structure exposure. was calculated using WildEST wildfire behavior results and the following wildfire response functions based on vegetation lifeform (Tree, shrub, grass):
Flame length probability of 0-2 ft: 25, 20, 10
Flame length probability of 2-4 ft: 40, 35, 20
Flame length probability of 4-6 ft: 55, 50, 40
Flame length probability of 6-8 ft: 70, 65, 55
Flame length probability of 8-12 ft: 85, 80, 70
Flame length probability of >12 ft: 100, 95, 85
These results were calculated using WildEST wildfire behavior results and then further smoothed. A cRPS value of 0 means no damage to a structure, and a value of 100 means complete loss.
