Abstract

Based on satellite measurements with OMI (NASA, USA) instrumentation in 2005–2023, total ozone (TO) monthly means for the warm season (April–September) and TO means for April–September and May–July periods have been calculated for nine locations on the territory of Russia in the latitude band 59°–65° N. Their linear trends have been estimated by the least-squares method. All TO trends have proved to be statistically insignificant and showed seasonal and longitudinal variability. In April, the trends at most locations are negative, while those in September are positive. For pairs of neighboring locations, the seasonal dependencies of TO trends usually correlate. Within the selected latitude range, dependence of TO trends on latitude is seen only in April.
