Abstract. The CRESTech Lidar Laboratory in collaboration with the Meteorological Service of Canada has been operating an ozone Raman DIAL system at Eureka in the Canadian High Arctic for successive 8 winters where ozone, temperature and aerosol measurements have been made. These data have revealed some very interesting trends over this observation period. These trends and the dynamic behaviour of these parameters in relation to the variability of the wintertime polar vortex will be presented in this paper. Ozone depletion over several winters will be discussed in relation to cold temperatures in the stratosphere that lead to the formation of Polar Stratospheric Clouds.
