===============================================================

.. py:function:: earthkit.meteo.thermo.array.mixing_ratio_from_specific_humidity(q)

   Compute the mixing ratio from specific humidity.

   :param q: Specific humidity (kg/kg)
   :type q: :class:`number` or :class:`array-like`

   :returns: Mixing ratio (kg/kg)
   :rtype: :class:`number` or :class:`array-like`

   The result is the mixing ratio in kg/kg units. The computation is based on
   the following definition [Wallace2006]_:

   .. math::

       w = \frac {q}{1-q}
