Trend and seasonal variation of atmospheric mercury concentrations at the Cape Point GAW observatory, South Africa
Gaseous elemental mercury (GEM) has been measured at the WMO Global Atmospheric Watch station at Cape Point, South Africa since September 1995. Two techniques were used: a low resolution manual technique till the end of 2004 and a high resolution automated technique since March 2007. The GEM measure...
