earthkit.climate.atmos.last_spring_frost(tasmin: xarray.DataArray | str = 'tasmin', ds: xarray.Dataset | Any = None, *, thresh: Any = '0 degC', op: Literal['<', 'lt', '<=', 'le'] = '<', before_date: str = '07-01', window: int = 1, freq: str = 'YS', **kwargs: Any) → Any

Last spring frost.

The last day when minimum temperature is below a given threshold for a certain number of days, limited by a final calendar date.

Units:

• last_spring_frost: dimensionless

This function wraps xclim.indicators.atmos.last_spring_frost.

Parameters:

• tasmin (xarray.DataArray | str) – Mean daily temperature.

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

• op (Literal[``’<’, ``'lt', '<=', 'le']) – Comparison operation. Default: “<”.

• before_date (str) – Date of the year before which to look for the final frost event. Should have the format ‘%m-%d’.

• window (int) – Minimum number of days with temperature below the threshold needed for evaluation.

• freq (str) – Resampling frequency.

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

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

Returns:

The computed index.

Return type:

Any
