Numerical Simulation of Tropospheric Ozone Depletion Events in the Arctic Spring of the Year 2019 ...
Ozone depletion is not only observed in the polar stratosphere, but also near the ground. Bromine species originating from sea salt are released from snow in an auto-catalytic reaction cycle and can then deplete ozone, strongly altering the oxidation capacity of the atmosphere. In this study, ozone...
