Automated BFB - What it needs (inputs)

Like BEHAVE and BehavePlus, WFDSS Basic Fire Behavior (BFB) requires the following information to perform fire behavior calculations:

WFDSS BFB automatically provides nearly all of the necessary information to perform fire behavior calculations.

Caution: The quality of the output from the analysis is only as good as the data input into the model. Before using the output results to support wildland fire decision-making, be sure that you understand the inputs: fuels data being used, the appropriateness of the RAWS from which fuel moistures are calculated, and the validity of the weather forecast data.

The following table lists the inputs required for the automated WFDSS Basic Fire Behavior model:



 Editable Value

Landscape data


Can choose to use the default LANDFIRE 2010 1.2.0 landscape data source or choose a different data source from the Incident Information page (HOWEVER you may NOT edit).

Foliar Moisture Content

WFDSS default (100%)

Not Editable

Live fuel moistures

From the WFDSS-selected RAWS and based on the standard NFDRS algorithms

Not Editable

Weather observations (for 7-day fuel moisture conditioning of dead fuels)

Nearby RAWS*

Not Editable

Weather forecast information for fire behavior predictions

National Digital Forecast Data (NDFD) based on the RAWS location

Not Editable

Wind speed and direction forecast information for fire behavior predictions

(wind speed and direction values are used as inputs to generate gridded winds)

National Digital Forecast Data (NDFD) based on the center of the user-defined landscape extent

Can change:

  • wind speed
  • wind direction

Landscape extent

(extent of analysis area)


Draw the landscape extent (normally no more than 5-6 miles per side)

Name of analysis


Name the analysis

Analysis Date and Time 


Enter the analysis date and time

 * WFDSS chooses the nearby RAWS in the following way:  The center of the analysis area is used as a starting point.  Then, a horizontal/vertical distance algorithm sorts the RAWS stations within a given area.  Next, WFDSS iterates through the list until the first station is found with the requisite fuel moisture / weather information (continuous hourly observations).
