TL;DR: In this paper, the GOME-2 satellite data was used to analyze the tropospheric BrO columns and the results showed that most BrO hotspots are of troposphere origin, although they are often associated to regions with low tropopause heights.

TL;DR: In this paper, an improved GOME-2 NO2 retrieval is described which reduces the scatter of the individual NO2 columns globally but in particular in the region of the Southern Atlantic Anomaly.

TL;DR: In this article, the authors derived a simple model to consider the environmental conditions that favour ozone depletion events and find two maxima, one at low wind/stable boundary layer and one at high wind speeds with blowing snow.

TL;DR: In this paper, a cyclone with very high surface wind speeds was linked to the production and lifting of aerosols or blowing snow, which could have been involved in the production of reactive halogen oxides like bromine monoxide (BrO).

TL;DR: In this article, satellite observations of iodine monoxide and bromine monoxide (BrO) and compared to the distributions of BrO are presented and the influence of the IO air mass factor and the IO absorption cross section temperature dependence on the absolute vertical columns are discussed.
