Short summary
We use a model of mercury chemistry and transport in the atmosphere, along with ground- and aircraft-based mercury observations, to learn that oxidized mercury chemically produced in the free troposphere descends in the subtropical anticyclones and makes up much of the mercury depositing to the Earth's surface. Our findings imply that mercury chemistry in the free troposphere and transport in the subtropics are important links between global emissions and surface deposition of mercury.
