Abstract

Lidar observations of stratospheric ozone, aerosol and temperature have been carried out at Toronto (43.8 N, 79.5 W) since 1989 and during winter months at the Arctic Stratospheric Observatory (AStrO) at Eureka (80 N, 86 W) since 1992. The Raman DIAL (Differential Absorption Lidar) systems utilized at both observatories are briefly described and the measurements are discussed. The measurements of AStrO are discussed in relation to the dynamics of stratospheric polar vortex and the presence of polar stratospheric clouds (PSC). Results from the winters of 1994/95 and 1995/96 indicate very low polar stratospheric temperatures, capable of inducing PSCs and exhibit an appreciable ozone depletion.
