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

.. py:function:: earthkit.meteo.solar.array.cos_solar_zenith_angle_integrated(begin_date, end_date, latitudes, longitudes, *, intervals_per_hour=1, integration_order=3)

   Average of solar zenith angle based on numerical integration.

   :param begin_date:
   :type begin_date: :class:`datetime.datetime`
   :param end_date:
   :type end_date: :class:`datetime.datetime`
   :param lat: Latitude [degrees].
   :type lat: :class:`array-like`
   :param lon: Longitude [degrees].
   :type lon: :class:`array-like`
   :param intervals_per_hour: Number of time integrations per hour.
   :type intervals_per_hour: :class:`int`
   :param integration order: Order of Gaussian integration, valid = (1, 2, 3, 4)
   :type integration order: :class:`int`

   :returns: Average of cosine of the solar zenith angle during interval [degrees]. Based on
             numerical integration using the 3 point [Gaussian_Quadrature]_ rule.
