Short summary
Within the EU-funded project, Global Mercury Observation System (GMOS) airborne mercury has been monitored at the background Råö measurement site on the western coast of Sweden from May 2012 to the end of May 2015, the following mercury species/fractions were measured: gaseous elemental mercury (GEM), particulate bound mercury (PBM) and gaseous oxidised mercury (GOM). Evidence that a significant part of the GOM measured at the Råö site has been formed in the free tropospheric air is presented.
