Pollution impacts on Arctic O3 and CO distributions during POLARCAT summer campaign.
International audience The Arctic ozone budget is not well quantified and global models fail to reproduce seasonal cycles especially in summertime when anthropogenic and boreal forest fire emissions can contribute. One possible explanation is the underestimation of modelled ozone production in fores...
