The report presents the measurements of ozone, non-methane hydrocarbons, sulphate, ammonium, halocarbons and meteorological parameters from Spitsbergen in the Norwegian Arctic. The presented data cover the spring period for several years. The focus of this study is the rapid depletion of ozone in the lower troposphere in the spring observed in Ny-Aalesund and on the nearby Zeppelin Mountain. Such depletion is also observed in other parts of the Arctic. The aim is to explore the physical and chemical environment in which the ozone depletion is taking place, and to make statements about mechanisms which can cause the depletion. It has also been important to get an indication of the magnitide of the ozone loss process in a qualitative sense. 23 refs., 12 figs., 9 tabs.
