Long-term time series of Arctic tropospheric BrO derived from UV-VIS satellite remote sensing and its relation to first-year sea ice

Bougoudis et al. 2020

 

Bromine molecules, released from the cryosphere, play an important role for the oxidizing capacity of the Arctic, as they deplete ozone, forming bromine monoxides (BrO). A new study presents the first long-term consistent tropospheric BrO dataset for the Arctic, retrieved from four satellite remote sensing instruments. It shows an increase of tropospheric BrO of approximately 1.5% per year during polar springs, under the impact of climate warming. It infers a moderate correlation to first year sea ice extent, suggesting that the increased formation of young sea ice plays a role to the enhanced appearance of BrO plumes.
