Fire season mask.

Binary mask of the active fire season, defined by conditions on consecutive daily temperatures and, optionally, snow depths.

Units:

  • fire_season: dimensionless

This function wraps xclim.indicators.atmos.fire_season.

Parameters:

  • tas (xarray.DataArray | str) – Daily surface temperature, cffdrs recommends using maximum daily temperature.

  • snd (xarray.DataArray | str | None) – Snow depth, used with method == ‘LA08’.

  • method (str) – Which method to use. “LA08” and “GFWED” need the snow depth.

  • freq (str | None) – If given only the longest fire season for each period defined by this frequency, Every “seasons” are returned if None, including the short shoulder seasons.

  • temp_start_thresh (Any) – Minimal temperature needed to start the season. Must be scalar.

  • temp_end_thresh (Any) – Maximal temperature needed to end the season. Must be scalar.

  • temp_condition_days (int) – Number of days with temperature above or below the thresholds to trigger a start or an end of the fire season.

  • snow_condition_days (int) – Parameters for the fire season determination. See fire_season(). Temperature is in degC, snow in m. The snow_thresh parameters is also used when dry_start is set to “GFWED”.

  • snow_thresh (Any) – Minimal snow depth level to end a fire season, only used with method “LA08”. Must be scalar.

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

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

Returns:

The computed index.

Return type:

Any
