ppcpy.retrievals.quasiV1.quasi_bsc(data_cube)

ppcpy.retrievals.quasiV1.quasi_retrieval(height, att_beta, molExt, molBsc, LRaer, nIters=2)

Retrieve aerosol optical properties using the quasi-retrieving method.

Parameters:

• height (array) – Height in meters [m].

• att_beta (ndarray) – Attenuated backscatter [m^{-1}Sr^{-1}].

• molExt (ndarray) – Molecular extinction coefficient [m^{-1}].

• molBsc (ndarray) – Molecular backscatter coefficient [m^{-1}Sr^{-1}].

• LRaer (float) – Aerosol lidar ratio [Sr].

• nIters (int, optional) – Number of iterations (default is 2).

Returns:

Quasi particle backscatter coefficient [m^{-1}Sr^{-1}]. quasi_par_ext (ndarray):

Quasi particle extinction coefficient [m^{-1}].

Return type:

quasi_par_bsc (ndarray)
