Weather Potential in August
U.S. Department of the Interior (DOI), Bureau of Land Management (BLM), Idaho State Office
As used in this assessment, "fire weather" is analogous to "extreme fire weather potential" used by Schmidt et al. (2002). The 3 main components of fire weather include temperature, humidity, and wind. We used average maximum temperature and average humidity (vapor pressure) for the month of August from DAYMET (http://www.ntsg.umt.edu/); and average surface wind speed for August from the ICBEMP (www.icbemp.gov). These data were 1000-m and 9317-m resolution, respectively. We "smoothed" the wind data by resampling it to 1000-m resolution so that it would have a similar resolution as the temperature and humidity data.
A proxy for fire weather was then generated spatially by averaging the standardized values for the 3 weather variables:
Wx_potential = (max_temp + (1- rel_humidity) + rel_wind_ros) / 3Access these Data:ESRI GRID
