+    r'''
+    Calculate cell temperature using the Ross model.
+
+    The Ross model [1]_ assumes the difference between cell temperature
+    and ambient temperature is proportional to the plane of array irradiance,
+    and assumes wind speed of 1 m/s. The model implicitly assumes steady or
+    slowly changing irradiance conditions.
+
+    Parameters
+    ----------
+    poa_global : numeric
+        Total incident irradiance. [W/m^2]
+
+    temp_air : numeric
+        Ambient dry bulb temperature. [C]
+
+    noct : numeric
+        Nominal operating cell temperature [C], determined at conditions of
+        800 W/m^2 irradiance, 20 C ambient air temperature and 1 m/s wind.
+
+    Returns
+    -------
+    cell_temperature : numeric
+        Cell temperature. [C]
+
+    Notes
+    -----
+    The Ross model for cell temperature :math:`T_{C}` is given in [1]_ as
+
+    .. math::
+
+        T_{C} = T_{a} + \frac{NOCT - 20}{80} S
+
+    where :math:`S` is the plane of array irradiance in :math:`mW/{cm}^2`.
+    This function expects irradiance in :math:`W/m^2`.
