Description
Summary:and comparisons with BrO vertical column densities obtained by the GOME (Global Ozone Monitoring Experiment) instrument aboard the earth remote sensing satellite ESR-2 indicates that the air masses exhibiting low Hg 0 concentrations originated from areas with high BrO densities. It was concluded that the observed depletion events at Ny- ° Alesund were a results of transport from areas with high photochemical activity around the polar region.
