The purpose of the Texas Wildfire Hazard Assessment (TxWRAP) is to provide foundational information about wildfire hazard across all land ownership in the state of Texas. Such information supports fuel management planning decisions, as well as revisions to land and resource management plans. A wildfire hazard assessment is a quantitative analysis of potential impacts by wildfire.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>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).</SPAN></P><P><SPAN STYLE="font-weight:bold;">This ember load dataset represents the expected ember load index (ELI), or expected relative ember load per pixel, for a given pixel, based on surface and canopy fuel characteristics, climate, and topography within the pixel. Units are relative number of embers.</SPAN></P><P><SPAN STYLE="font-weight:bold;">ELI can be used to identify where on the landscape hardening buildings may be needed to resist ignition and the priority for doing so according to the likelihood of the area being visited by fire.</SPAN></P><P><SPAN STYLE="font-weight:bold;">ELI is not simply the multiplication of condition ember load (cELI) and burn probability (BP). Rather, BP is incorporated into calculations of the ember production prior to the distribution of embers across the landscape to determine ember load.</SPAN></P><P><SPAN STYLE="font-weight:bold;">ELI is based on heading-only fire behavior.</SPAN></P></DIV></DIV></DIV>
