earthkit.meteo.solar.xarray.solar_declination_angle

earthkit.meteo.solar.xarray.solar_declination_angle(date)

Compute the solar declination angle and time correction.

Parameters:

date (xarray.DataArray) – Date/time. Computation is performed element-wise.

Returns:

• xarray.DataArray – Solar declination angle (degrees).

• xarray.DataArray – Time correction (degrees).

Return type:

tuple[xarray.DataArray, xarray.DataArray]

Notes

This function returns two outputs. We explicitly provide output_dtypes to ensure xarray correctly allocates the outputs when vectorizing.
