Description

Function fuel_windAdjustmentFactor determines the adjustment factor of wind for surface fires, according to Andrews (2012).

Usage

  topCanopyHeight,
  canopyCover
)

Arguments

topShrubHeight	Shrub stratum top height (in m).
bottomCanopyHeight	Canopy base height (in m).
topCanopyHeight	Canopy top height (in m).
canopyCover	Canopy percent cover.

Value

A scalar value between 0 and 1
