Motivation and Goals Motivation and Goals
• Establish long-term data record of ambient Establish long-term data record of ambient concentrations (Hgconcentrations (Hg00, RGM, FPM) & Wet Deposition, RGM, FPM) & Wet Deposition
• Discern trends in atmospheric concentrationsDiscern trends in atmospheric concentrations
• Correlation with ancillary trace species to better Correlation with ancillary trace species to better understand the origins and chemical cycling of understand the origins and chemical cycling of mercury in the atmospheremercury in the atmosphere
• Data set for model evaluation Data set for model evaluation
