Wet deposition of mercury at Lhasa, the capital city of Tibet

► A 1-year dataset of wet Hg deposition is presented for Lhasa, Tibet. ► HgR concentrations were higher during the monsoon season. ► HgP dominated the concentration and flux of HgT in the wet-deposition samples. ► HgT concentration was the major factor governing HgT wet deposition. ► Estimates by the GEOS-Chem model were higher than the observed annual Hg wet flux.
