Plot a): Relationships of modeled Hg dry deposition fluxes with elevation (GEM left axis, GOM and PBM right axis).

<p>The logistic equations used are shown in SI Table A. Plot b): The effect of the scaling factor () on the modeled dry Hg deposition, and the comparisons with field data (solid lines: modeled dry deposition; while the dotted, dashed, and dash-dotted lines: the field data of litterfall Hg deposition and the sum of litterfall (LF) and net throughfall (TF) Hg deposition, respectively). Note that the net throughfall Hg for deciduous forest is small, with the values for LF Hg deposition and the sum of LF and TF Hg deposition as 14.7 g m yr and 14.9 g m yr, respectively. In this study, we used a value of 0.1, and the corresponding modeled dry Hg deposition to coniferous (dark green triangle symbol) and deciduous (blue triangle symbol) forests were: 17.5 g m yr and 12.4 g m yr, respectively. The blue circle that nearly supersedes the dark green triangle represents the modeled net dry Hg deposition to deciduous forest (17.9 g m yr).
