| description | Atmospheric chemistry and transport
of mercury play a key role in the global mercury cycle. However, there are
still considerable knowledge gaps concerning the fate of mercury in the
atmosphere. This is the second part of a model intercomparison study
investigating the impact of atmospheric chemistry and emissions on mercury in
the atmosphere. While the first study focused on ground-based observations of
mercury concentration and deposition, here we investigate the vertical and
interhemispheric distribution and speciation of mercury from the planetary
boundary layer to the lower stratosphere. So far, there have been few model
studies investigating the vertical distribution of mercury, mostly focusing
on single aircraft campaigns. Here, we present a first comprehensive analysis
based on various aircraft observations in Europe, North America, and on
intercontinental flights.

The investigated models proved to be able to reproduce the distribution of
total and elemental mercury concentrations in the troposphere including
interhemispheric trends. One key aspect of the study is the investigation
of mercury oxidation in the troposphere. We found that different chemistry
schemes were better at reproducing observed oxidized mercury patterns
depending on altitude. High concentrations of oxidized mercury in the upper
troposphere could be reproduced with oxidation by bromine while elevated
concentrations in the lower troposphere were better reproduced by OH and
ozone chemistry. However, the results were not always conclusive as the
physical and chemical parameterizations in the chemistry transport models
also proved to have a substantial impact on model results. |
