Paper Abstract

Mercury is the only atmospheric pollutant that is present in the atmosphere in atomic form. Range-resolved Hg mapping can be performed using the differential absorption lidar (dial) technique employing the 254 nm Hg resonance line. We have used the lidar technique both for mapping of industrial plumes and for background concentration measurements. Our studies also include mercury of geophysical origin. A field test has been performed in Icelandic geothermal fields. We have also attempted studies of Hg emission from lake surfaces.
