earthkit.climate.atmos.temperature.growing_season_length

earthkit.climate.atmos.temperature.growing_season_length(tas: xarray.DataArray | str = 'tas', ds: xarray.Dataset | Any = None, *, thresh: Any = '5.0 degC', window: int = 6, mid_date: str | None = '07-01', freq: str = 'YS', op: Literal['>', 'gt', '>=', 'ge'] = '>=', **kwargs: Any) Any

Growing season length.

Number of days between the first occurrence of a series of days with a daily average temperature above a threshold and the first occurrence of a series of days with a daily average temperature below that same threshold, occurring after a given calendar date.

Units:

  • growing_season_length: days

This function wraps xclim.indicators.atmos.growing_season_length.

Parameters:
  • tas (xarray.DataArray | str) – Mean daily temperature.

  • thresh (Any) – Threshold temperature on which to base evaluation.

  • window (int) – Minimum number of days with temperature above the threshold to mark the beginning and end of growing season.

  • mid_date (str | None) – Date of the year before which the season must start and after which it can end. Should have the format ‘%m-%d’. Setting None removes that constraint.

  • freq (str) – Resampling frequency.

  • op (Literal[``’>’, ``'gt', '>=', 'ge']) – Comparison operation. Default: “>=”.

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

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

Returns:

The computed index.

Return type:

Any
