High Resolution Weather for Fire Risk Assessment
In practice, current fire model runs typically use weather data from a remote automatic weather station (RAWS). Numerous RAWS have been deployed among the nation's forests and wildlands, expressly for the purpose of determining daily fire danger. However, fire danger assessment operates at a much coarser spatial/temporal scale than fire behavior modeling (10s of kilometers vs. meter scale, daily vs. hourly frequency). The high resolution weather models used by PSW produce gridded weather fields for the FARSITE fire modeling system at 1-4 kilometer intervals and hourly time steps, for an area measuring 10s of kilometers on each side. The models simulate weather variability owing to mountains, large water bodies, land cover characteristics, large-scale and upper atmosphere weather patterns, and more. PSW scientists and their partners have developed these models over time especially for fire danger and fire behavior prediction.
