Abstract
The study of the field of total ozone column (TOC) is one of the important problems of atmospheric optics. In this paper, the spatial distribution of TOC over the Russian territory is analyzed based on Aura/OMI (Ozone Monitoring Instrument) data. The observation results for individual areas (points) are presented in the form of TOC time series, which cover the observation period from January 2005 to December 2022. Integral (excluding seasonal variations) latitude-longitude features of TOC distribution over the territory under study are revealed; correlation coefficients between the TOC series for different points are calculated; their relationship is studied depending on the distance between the points; the spatial autocorrelation function is derived and the sizes of spatial inhomogeneities of the TOC field are estimated. The spatial mismatch of the data is analyzed using a parameter which is 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 component of the atmosphere when developing weather and climate change prognostic models.
