xrspatial.fire.flame_length#

xrspatial.fire.flame_length(intensity_agg: DataArray, name: str = 'flame_length') → DataArray[source]#

Flame length from fireline intensity.

Uses Byram’s equation: L = 0.0775 * I^0.46. Negative or zero intensity yields zero flame length.

Parameters:

  • intensity_agg (xr.DataArray or xr.Dataset) – Fireline intensity (kW/m).

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

Returns:

Flame length in metres (float32).

Return type:

xr.DataArray
