WindNinja is a computer program that computes spatially varying wind fields for wildland fire application. It requires elevation data for the modeling area (in the form of an ASCII Raster DEM file, FARSITE landscape file, GeoTiff, or ERDAS Imagine file), a domain-mean initial wind speed and direction, and specification of the dominant vegetation in the area. A diurnal slope flow model can be optionally turned on or off. Outputs of the model are ASCII Raster grids of wind speed and direction (for use in spatial fire behavior models such as FARSITE and FlamMap), a GIS shapefile (for plotting wind vectors in GIS programs), and a .kmz file (for viewing in Google Earth). WindNinja is typically run on domain sizes up to 50 kilometers by 50 kilometers and at resolutions of around 100 meters.

The installation program and accompanying files can be found on the Downloads page.
For incident support, please contact the WindNinja Team. |

WindWizard, a Gridded Wind Model, is a method that can provide information about the effect of topography on local wind flow at the 100-300 ft scale. Wind information at this detail is not available from the weather service. The wind simulations are not forecasts but rather simulations of what the wind flow would be under different general (synoptic) wind speed and direction scenarios.
For more information, look under Research Systems in the menu at the top of each page.
Note: WindWizard is no longer supported by the Missoula Fire Sciences Lab as the underlying software is not readily available. Much of the Computational Fluid Dynamics (CFD) modeling within the WindWizard framework will be added to WindNinja within the next two years.

FireStem is a computer model designed to aid fire managers in predicting tree mortality based on fire behavior and intensity.
The eventual goal is to produce mortality predictions based on fuel information, moisture, and fire behavior for a specified region and a range of tree species.
