pywasp.lincom.shear_exp_from_wspd

pywasp.lincom.shear_exp_from_wspd(wspd, height_map, w_map=None)

Calculate shear exponent using a linear log-log fit from a number of heights

Parameters:

• wspd (DataArray) – Wind Speeds with at least a height dimension

• height_map (dict) –

  Dictionary:

  • keys: a float providing the height of Alpha to be calculated

  • values: a list of the heights used to calculate Alpha, must be in wspd

• w_map (dict) – The same as height_map, but values should be the weights that are passed to the numpy.polyfit function.

Returns:

DataArray – DataArray of Alpha
