Polar boundary layer bromine explosion and ozone depletion events in the chemistry–climate model EMAC v2.52: implementation and evaluation of AirSnow algorithm
Publication date Mar 28 2018 Geosci. Model Dev.
Abstract Ozone depletion events (ODE) in the polar boundary layer are observed frequently in spring. ODE serve as source of tropospheric BrO at high latitudes. A treatment of bromine release and recycling on sea ice and snow covered surfaces has been implemented in global chemistry-climate model EMAC based on scheme of Toyota et al. (2011). Many aspects of bromine enhancement and associated ODE are reproduced in both polar regions. Further bromine release mechanisms can now be tested in a global model.
Brominated VSLS and their influence on ozone under a changing climate
Publication date Sep 25 2017 Atmospheric Chemistry and Physics
Abstract Brominated very short-lived source gases (VSLS) contribute significantly to the tropospheric and stratospheric bromine loading. We find an increase of future ocean-atmosphere flux of brominated VSLS of 8–10 % compared to present day. A decrease in the tropospheric mixing ratios of VSLS and an increase in the lower stratosphere are attributed to changes in atmospheric chemistry and transport. Bromine impact on stratospheric ozone at the end of the 21st century is reduced compared to present day.
