Stratospheric Ozone Variability over Spitsbergen in March – April 1991

Abstract The Finnish Meteorological Institute, the Alfred Wegener Institute and Bremen University jointly performed upper atmospheric soundings from Ny Ålesund, Spitsbergen (79°N, 12°E) between March 11 and April 24, 1991. The soundings were made using Vaisala radiosondes and ECC ozone sondes and pr...

Description
Summary:Abstract The Finnish Meteorological Institute, the Alfred Wegener Institute and Bremen University jointly performed upper atmospheric soundings from Ny Ålesund, Spitsbergen (79°N, 12°E) between March 11 and April 24, 1991. The soundings were made using Vaisala radiosondes and ECC ozone sondes and produced a good picture of ozone behaviour in the lower and middle stratosphere. With one exception, the soundings were carried out daily or at least every other day with most of them reaching altitudes higher than 30 km. – The temperature record reveals that in the middle of the experiment stratospheric warming took place. The warming was also reflected in the rising trend of total ozone. In addition to this transition from winter to spring conditions in the polar stratosphere, there was also considerable variability in both the total ozone content and the vertical variability of ozone concentrations. The reasons for these seem to be to a large extent dynamical in origin.
