Multi-model study of mercury dispersion in the atmosphere: atmospheric processes and model evaluation

Publikováno v: Atmospheric Chemistry and Physics, Vol 17, Iss 8, Pp 5271-5295 (2017)

Current understanding of mercury (Hg) behavior in the atmosphere contains significant gaps. Some key characteristics of Hg processes, including anthropogenic and geogenic emissions, atmospheric chemistry, and air–surface exchange, are still poorly

Five-year records of mercury wet deposition flux at GMOS sites in the Northern and Southern hemispheres

Publikováno v: Atmospheric Chemistry and Physics, Vol 17, Iss 4, Pp 2689-2708 (2017)

The atmospheric deposition of mercury (Hg) occurs via several mechanisms, including dry and wet scavenging by precipitation events. In an effort to understand the atmospheric cycling and seasonal depositional characteristics of Hg, wet deposition sam
