A comprehensive analysis of the temporal evolution of tropospheric ozone in Antarctica using more than 25 years of surface ozone and ozonesonde measurements reveals significant changes in tropospheric ozone there. It shows a positive trend in ozone at the surface and lower and mid-troposphere, but a negative trend in the upper troposphere. We also find significant links between different climate modes and tropospheric ozone in Antarctica and observe that changes in residual overturning circulation, the strength of the polar vortex, and stratosphere–troposphere exchange make noticeable variability in tropospheric ozone. Therefore, this study alerts of increasing ozone concentration in Antarctica, which would have a profound impact on the future climate of the region as tropospheric ozone has warming feedback to the Earth’s climate.

南极洲地表臭氧和对流层臭氧增加及其可能的驱动因素

使用超过 25 年的地表臭氧和臭氧探空仪测量结果对南极洲对流层臭氧的时间演变进行了综合分析，揭示了那里对流层臭氧的显着变化。它显示出地表和对流层低层和中层臭氧呈正趋势，但在对流层高层呈负趋势。我们还发现南极洲不同气候模式与对流层臭氧之间存在显着联系，并观察到残余翻转环流、极地涡旋强度和平流层-对流层交换的变化使对流层臭氧发生显​​着变化。因此，这项研究提醒了南极洲臭氧浓度的增加，这将对该地区未来的气候产生深远的影响，因为对流层臭氧对地球气候有变暖的反馈。
