Carbonate precipitation in brine – a potential trigger for tropospheric ozone depletion events
Carbonate precipitation potential trigger tropospheric ozone depletion events
2009/1/16
Tropospheric ozone depletion events (ODEs) at high latitudes were discovered 20 years ago and are attributed to bromine explosions. However, an unresolved issue is the explanation of how the acid-cata...
