Description: 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 dataset represents a classification of the land near and surrounding buildings into zones that describe the wildfire risk mitigation activities appropriate for each zone. 1: Direct Exposure--Burnable land cover within 75 m of a building > 40 m2. Buildings in this zone are exposed to ignition from convective and radiative heat from a wildfire, embers, and adjacent burning structures/outbuildings.2: Indirect Exposure--Nonburnable land cover within 75 m of a building > 40 m2 and less than 1530 m from a 500-ha contiguous block of wildland fuel. Buildings in this zone are exposed to ignition from embers and/or adjacent burning structures3: Little-to-no Exposure--Nonburnable land cover within 75 m of a building > 40 m2 and more than 1530 m from a 500-ha contiguous block of wildland fuel. Buildings in this zone are relatively safe from ember ignition and building-to-building spread. 4: Critical Fireshed--the burnable land cover from which a wildfire can reach a significant number of buildings within a single burning period.8: Sources of Ember Load to Buildings--Burnable land cover more than 75 m from a building > 40 m2 that produces embers capable of reaching nearby buildings. Ember production is a function of fire type and intensity; ember travel is a function of wind speed and direction. Ember modeling is based on fire modeling based on gridded historical climatology.
