WRF-SFIRE LES Synthetic Wildfire Plume Dataset

Description: The dataset consists of 147 large-eddy simulations of wildfire plumes produced with WRF-SFIRE LES, capturing a wide range of fire and atmospheric conditions. This synthetic dataset (147 NetCDF files) was produced using WRF-SFIRE model configured in idealized large-eddy resolving mode. Key parameters varied were ambient wind, fuel category, vertical potential temperature profile and fireline length, denoted as conditions W,F,R and L, respectively. Each 10 km x 20 km domain has 40 m horizontal grid spacing. Depending on the sounding R, the simulations were performed in either a shallow (3000 m) or a deep (5000 m) domain, with 51 or 71 hyperbolically stretched vertical levels, respectively. The files contained in this dataset were initialized from a restart file generated at the end of 1 h model spinup period. Each simulation is either 20 or 30 min in length, depending on initial conditions (see Data & File Overview in README.txt for further information). The fire was initialized over a one-minute interval using a straight line of length L. The ignition line was placed one kilometer downwind of the western edge of the domain (perpendicular to ambient wind) and centered in the north-south direction. With a refinement ratio of 10 in each horizontal direction, the fire was simulated on a 4 m sub-grid mesh. Full details of domain configuration are provided in: Moisseeva, Nadya, and Roland Stull.
