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

.. py:function:: earthkit.meteo.vertical.array.geopotential_height_from_geometric_height(h, R_earth=constants.R_earth)

   Compute the geopotential height from geometric height.

   :param h: Geometric height with respect to the sea level (m)
   :type h: :class:`array-like`
   :param R_earth: Average radius of the Earth (m)
   :type R_earth: :class:`float`, *optional*

   :returns: Geopotential height (m)
   :rtype: :class:`array-like`

   The computation is based on the following formula:

   .. math::

       gh = \frac{h\; R_{earth}}{R_{earth} + h}

   where :math:`R_{earth}` is the average radius of the Earth (see :py:attr:`meteo.constants.R_earth`)
