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 three fundamentally different approaches to derive the degree of chemical ozone loss from ozonesonde, balloon, aircraft, and satellite instruments and showed that the ozone losses derived from these different instruments and approaches agree very well, resulting in a high level of confidence in the results.

TL;DR: The MOSAiC program as mentioned in this paper was organized into four subgroups: atmospheric state, clouds and precipitation, gases and aerosols, and energy budgets, using a variety of approaches, and across multiple scales.

TL;DR: The Match technique was used to determine chemically induced ozone loss inside the stratospheric vortex during the Arctic winter 2002/2003 as mentioned in this paper, which is the earliest start of a Match campaign ever, until end of March 2003.

TL;DR: In this paper, the authors used three fundamentally different approaches to derive the degree of chemical ozone loss from ozonesonde, balloon, aircraft, and satellite instruments and showed that the ozone losses derived from these different instruments and approaches agree very well, resulting in a high level of confidence in the results.
