Abstract. A method is proposed for pre-processing of the registered spectra of different morphological types of clouds registered with 57-channel ground-based radiometer in the spectral range from 387 to 902 nm. The method consists of transforming the primary measured spectra to uniform experimental conditions and decreasing the dimension of the handled spectra through selection of the maximally informative spectral channels. The application of this pre-processing procedure minimizes the negative influence of a number of factors determining the experimental conditions.
