Short summary
Air–surface exchange of mercury is an important process for the movement of this toxic metal through the environment. This study presents observations of nocturnal depletion of atmospheric mercury, with surface deposition playing a large role. This deposited mercury is more labile, with up to ~17% re-released the following morning. This study is the first of its kind taken in Australia. Comparison with studies in the Northern Hemisphere shows reasonably good agreement for deposition velocities.
