Figure 3.
Averaged monthly observations and model simulations of Hg0 concentrations for the NADP AMNet ground-based sites.
Locations of the 11 remote/rural NADP AMNet sites are plotted in Figure 1. The thick black line and gray shaded region show the average and 1σ uncertainty range of observed Hg0 concentration in 2013. The thin black line shows the average observation in 2009–2012. The blue, green, and red solid lines indicate model results from REF, INV, and HOXSO, respectively. The dotted and dashed red lines indicate model results from HOX and HSO, respectively.
