All welcome. If external to BAS, please email the organiser in advance to gain access to the building.

In this presentation, I will introduce atmospheric bromine and its impact on atmospheric chemistry in both the troposphere and the stratosphere. The first part of the presentation will focus on very-short-lived bromocarbons and their effects on recovery of the stratospheric ozone hole. Then I will move to polar region to introduce ‘bromine explosion’ events and various mechanisms suggested in the past decades. To finish it, I will talk about uncertainties/difficulties in bromine simulation.
