Abstract

The study presents the results of analysis of observational data on total ozone (TO) at the Russian Antarctic stations Mirny, Novolazarevskaya, and Vostok for 1975–2019 and on the research vessels for 2005–2019. A steady trend towards the TO decrease in Antarctic spring was observed till the early 2000s. Currently, there is a tendency of returning TO values to those typical of the period preceding the manifestation of the ozone hole effect.

对南极洲及大西洋和南大洋的臭氧总量进行长期观测的结果

摘要

这项研究提出了1975-2019年俄罗斯南极Mirny，Novolazarevskaya和Vostok台站以及2005-2019年研究船上的总臭氧（TO）观测数据的分析结果。直到2000年代初，南极春季的TO一直呈稳定的下降趋势。当前，存在使TO值恢复到出现臭氧空穴效应之前的典型时期的趋势。
