In situ aircraft measurements of O-3, CO, HNO3, and aerosol particles are presented, performed over the North Sea region in the summer lower stratosphere during the STREAM II campaign (Stratosphere Troposphere Experiments by Aircraft Measurements) in July 1994. Occasionally, high CO concentrations of 200-300 pbbv were measured in the lowermost stratosphere, together with relatively high HNO3 concentrations up to 1.6 ppbv. The particle number concentration (at standard pressure and temperature) between 0.018-1 mu m decreased across the tropopause, from > 1000 cm(-3) in the upper troposphere to <500 cm(-3) in the lowermost stratosphere. Since the CO sources are found in the troposphere, the elevated CO mixing ratios are attributed to mixing o...
