A new technique is presented for processing data obtained from broad-band measurements of direct sunlight in order to increase the bulk of experimental information. The technique is based on the method of moments. It allows reconstruction of the total content of the gaseous constituent, the effective height of a layer, and its halfwidth. In order to reveal peculiarities and potentialities of the new technique as applied to reconstruction of the parameters sought, numerical simulations have been performed. Besides, the technique has been applied to process real data obtained with a M–124 ozonometer.
