Presented are the results of studies dealing with the analysis of discrepancies in the data on total ozone measurements carried out using different instruments. The results of measurements with ground-based spectral (UV and visible) and filter instruments and spaceborne nadir scanning instru¬ments are used as initial data. As a result of the analysis of relative systematic and random discrepan¬cies, it is concluded that the data of filter instruments are of insufficient accuracy for diagnosing total ozone values. The analysis of linear trends revealed the presence of considerable differences in the data series obtained by spectral instruments. It is concluded that there is every reason to hope for obtaining the most homogeneous measurement data in Russia using the instruments operating in the Chappuis band.
