What fuel moisture values are used in the Basic Fire Behavior (BFB) and Short-Term Fire Behavior (STFB) applications?
Dead fuel moisture values are calculated using fuel moisture conditioning, which is based on each cell’s aspect, elevation, and canopy cover, as well as the previous 7 days of RAWS weather data. BFB and STFB obtain live fuel moisture values from daily WFDSS ERC-G calculations via the WFDSS-selected RAWS. These values cannot be modified. However, they can be viewed (see Viewing WFDSS Automated Fire Behavor Inputs). Foliar moisture content is set to a default value of 100%, and this cannot be changed. Modifying live herbaceous, live woody, and foliar moisture content will likely be available in the future within the Analyst-Assisted versions of BFB and STFB. ———– Last updated on 5/18/2010 10:28:57 PM.

BFB and STFB obtain live fuel moisture values from daily WFDSS ERC-G calculations via the WFDSS-selected RAWS. These values cannot be modified in the automated version of BFB and STFB. However, they can be viewed (see Viewing WFDSS Automated Fire Behavor Inputs). In the analyst-assisted versions of BFB and STFB, the fuel moistures can be changed under the initial fuel moisture section. Foliar moisture content is set to a default value of 100%, and this cannot be changed in the automated BFB and STFB. In the analyst-assisted versions, foliar moisture can be set from 70-140%. ———– Last updated on 11/8/2010 12:24:38 PM.
