xrspatial.fire.fireline_intensity(fuel_consumed_agg: DataArray, spread_rate_agg: DataArray, heat_content: float = 18000.0, name: str = 'fireline_intensity') → DataArray[source]#

Byram’s fireline intensity.

I = H * w * R where H is heat content (kJ/kg), w is fuel consumed (kg/m^2), and R is rate of spread (m/s).

Parameters:

  • fuel_consumed_agg (xr.DataArray) – Fuel consumed per unit area (kg/m^2).

  • spread_rate_agg (xr.DataArray) – Rate of spread (m/s).

  • heat_content (float, default=18000) – Heat content of fuel (kJ/kg).

  • name (str, default='fireline_intensity') – Name of output DataArray.

Returns:

Fireline intensity in kW/m (float32).

Return type:

xr.DataArray
