earthkit.meteo.thermo.xarray.saturation_specific_humidity

earthkit.meteo.thermo.xarray.saturation_specific_humidity(t, p, phase='mixed')

Compute the saturation specific humidity from temperature with respect to a phase.

Parameters:

• t (xarray.DataArray) – Temperature (K)

• p (xarray.DataArray) – Pressure (Pa)

• phase (str, optional) – Define the phase with respect to the saturation_vapour_pressure() is computed. It is either “water”, “ice” or “mixed”.

Returns:

Saturation specific humidity (kg/kg)

Return type:

xarray.DataArray

Equivalent to the following code:

e = saturation_vapour_pressure(t, phase=phase)
return specific_humidity_from_vapour_pressure(e, p)
