Abstract
In this work, we present the time series of regular observations of the total ozone content over Tomsk with three independent instruments over the period from 2006 to 2020. The main statistical characteristics of these time series are determined. We carried out the comparative analysis of these time series with each other and, in particular, the analysis of long-term annual average behaviors. The causes for the discrepancies of these measurements are discussed.
