earthkit.meteo.thermo.xarray.specific_humidity_from_mixing_ratio(w)

Compute the specific humidity from mixing ratio.

Parameters:

w (xarray.DataArray) – Mixing ratio (kg/kg)

Returns:

Specific humidity (kg/kg)

Return type:

xarray.DataArray

The result is the specific humidity in kg/kg units. The computation is based on the following definition [Wallace2006]:

\[q = \frac {w}{1+w}\]
