Interactive comment on “Surface deposition of oxidized mercury dominated by production in the upper and middle troposphere” by Viral Shah and Lyatt Jaeglé

This paper investigates – using the GEOS-Chem global chemical transport model how surface deposition of divalent mercury species (Hg(II)) is influenced by Hg(II) production at different atmospheric heights. The authors show that surface deposition is dominated by production in the upper and middle troposphere and highlight the large role of subtropical anticyclones as a global reservoir of Hg(II). This study also shows that regional decreases in anthropogenic mercury emissions will not lead to a proportional regional decrease in wet deposition. The paper is organized clearly, easy to follow, well written, and will make a valuable contribution to the literature. However, I find the evaluation of the model with observations insufficient and not up to date. This
