Chemical Evolution of the Exceptional Arctic Stratospheric Winter 2019/2020 Compared to Previous Arctic and Antarctic Winters
; ; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Atmospheres, 2021-09-21)
The winter 2019/2020 showed the lowest ozone mixing ratios ever observed in the Arctic winter stratosphere. It was the coldest Arctic stratospheric winter on record and was characterized by an unusually strong and long‐lasting ... -
Near-Complete Local Reduction of Arctic Stratospheric Ozone by Severe Chemical Loss in Spring 2020
; ; Lehmann, R.; ; ; ; Davies, J.; ; Jepsen, N.; ; Lyall, N.; Rex, M. (Geophysical Research Letters, 2020)
In the Antarctic ozone hole, ozone mixing ratios have been decreasing to extremely low values of 0.01–0.1 ppm in nearly all spring seasons since the late 1980s, corresponding to 95–99% local chemical loss. In contrast, ...
