ppcpy.retrievals.angstroem.ae_cldFreeGrps(data_cube, ret_prof_name)[source]#: convention for now to store the AE in the channel of the lower of the two wavelengths

ppcpy.retrievals.angstroem.calc_ae(param1, param1_std, param2, param2_std, wavelength1, wavelength2, smooth_window=17)[source]#

calculates the Ångström exponent and its uncertainty.

USAGE:

angexp, angexpStd = pollyAE(param1, param1_std, param2, param2_std, wavelength1, wavelength2)

INPUTS:

param1: array: Extinction or backscatter coefficient at wavelength1.
param1_std: array: Uncertainty of param1.
param2: array: Extinction or backscatter coefficient at wavelength2.
param2_std: array: Uncertainty of param2.
wavelength1: float: The wavelength for the input parameter 1. [nm]
wavelength2: float: The wavelength for the input parameter 2. [nm]
smooth_window: int, optional: The width of the smoothing window (default: 17).
