Bromine Oxide (L2__BRO___)

The TROPOMI Bromine Monoxide (BrO) total vertical column product was developed for the monitoring of the daily global spatial and temporal distribution of this trace gas in the Earth's atmosphere.

Inorganic bromine plays an important role in the chemistry of the atmosphere. Bromine monoxide contributes to mid-latitude ozone loss and to polar ozone depletion in the stratosphere. In the troposphere, BrO is released over sea ice covered regions every polar spring and the resulting chemical reactions contribute to ozone depletion and mercury deposition. BrO can further be found over salt lakes and in volcanic plumes.
