Short summary
We investigate emissions of brominated gases from the ocean and their contribution to stratospheric ozone depletion. Once in the atmosphere, these gases usually break down in less than 6 months. Their impact on the ozone layer depends on the prevailing atmospheric circulation, since transport to the stratosphere requires uplift. We combine aircraft and ship observations with atmospheric modelling to analyse how, where, and when these gases are transported from the ocean into the stratosphere.
