TL;DR: In this paper, the authors conducted quality assurance experiments of electrochemical concentration cell (ECC) ozonesondes of two different model types (SPC-6A and ENSCI-Z) under the framework of the Juelich Ozone Sonde Intercomparison Experiment (JOSIE).

TL;DR: The 1980s regime shift represented a major change in the Earth's biophysical systems from the upper atmosphere to the depths of the ocean and from the Arctic to the Antarctic, and occurred at slightly different times around the world.

TL;DR: In this paper, the authors report evidence from multiple satellite measurements that ozone in the lower stratosphere between 60°S and 60°N has indeed continued to decline since 1998, and they find that, even though upper stratospheric ozone is recovering, the continuing downward trend in the upper stratosphere prevails, resulting in a downward trend of ozone between 60 − 90°N and 60 − 80°N.

TL;DR: In this article, the Arctic polar vortex exhibited widespread regions of low temperatures during the winter of 2005, resulting in significant ozone depletion by chlorine and bromine species, and the volume of Arctic vortex air cold enough to support the existence of polar stratospheric clouds.

TL;DR: In this article, the authors used ozone observations from sondes, regular aircraft, and alpine surface sites in a self-consistent analysis to determine robust changes in the time evolution of ozone over Europe.
