Mcarthur forest fire danger index (ffdi) mark 5.

The FFDI is a numeric indicator of the potential danger of a forest fire.

Units:

  • ffdi: dimensionless

This function wraps xclim.indicators.atmos.mcarthur_forest_fire_danger_index.

Parameters:

  • drought_factor (xarray.DataArray | str) – The drought factor, often the daily Griffiths drought factor (see griffiths_drought_factor()).

  • tasmax (xarray.DataArray | str) – The daily maximum temperature near the surface, or similar. Different applications have used different inputs here, including the previous/current day’s maximum daily temperature at a height of 2m, and the daily mean temperature at a height of 2m.

  • hurs (xarray.DataArray | str) – The relative humidity near the surface and near the time of the maximum daily temperature, or similar. Different applications have used different inputs here, including the mid-afternoon relative humidity at a height of 2m, and the daily mean relative humidity at a height of 2m.

  • sfcWind (xarray.DataArray | str) – The wind speed near the surface and near the time of the maximum daily temperature, or similar. Different applications have used different inputs here, including the mid-afternoon wind speed at a height of 10m, and the daily mean wind speed at a height of 10m.

  • ds (xarray.Dataset | Any) – Input dataset.

  • **kwargs (Any) – Additional keyword arguments.

Returns:

The computed index.

Return type:

Any
