Specific Features of Distribution of Total Ozone Column Field over the Territory of Russia, its Interrelations, and Data Mismatch

Abstract

The studies of the total ozone column (TOC) field are among the important problems of atmospheric optics. In this paper, the spatial distribution of the TOC over Russian territory is analyzed based on Aura OMI (Ozone Monitoring Instrument) data. The observations for individual areas (sites) are presented in the form of TOC time series, which cover the observation period from January 2005 to December 2022. Integrated (without accounting for the seasonal variations) latitude–longitude features of TOC distribution over the territory under study are revealed; correlation coefficients between the TOC time series for different sites are calculated; their interrelations are studied as functions of the distance between the sites; the spatial autocorrelation function is compiled and the sizes of the spatial inhomogeneities of the TOC field are estimated. The spatial mismatch of the data is analyzed using a parameter representing a measure of the standard deviation from the average mismatch. The results of the work provide an idea of the scale of the spatial correlations in the TOC field and can be used for clarifying the optically active constituent of the atmosphere when developing weather and climate change prognostic models.
