Abstract:

A method for estimating the total O₃ and NO₂ content (TC) from measurements of the spectral sky brightness in the zenith is briefly described. Possible errors in reconstructing the TC using two- and four-wavelength differential absorption methods based on the single-scattering model have been thoroughly accounted. The idea of scanning over the spectrum of pairs of wavelengths used for data processing has been realized that allows us to perform statistically vivid reconstruction of the TC of gases under study. Results of numerical calculation of errors in the TC reconstruction have been presented for the case of processing of real signals recorded in the 280–450 nm wavelength range in the daytime over Tomsk. The mean values of relative errors in the TC reconstruction are about 5–7% for ozone and 40–76% for nitrogen dioxide.
