geodata.wind.psi_linear
=======================

.. py:function:: geodata.wind.psi_linear(z, ds)

   NOTE: This function does not perform well for high z/L
   Linear stability correction [1,2]
           z = to_height
           ds = dataset with variables: L

   Eval =      0, if z/L <=0
                   linear if z/L > 0
