Abstract. The York/ISTS lidar group has operated a differential absorption lidar (DIAL) system at the Eureka observatory in the Canadian High Arctic (80N, 86W) for the last four winters. For the 1994/95 and 1995/96 winters notable declines in stratospheric ozone levels have been observed. Correlation of ozone measurements with stratospheric aerosol observations and potential vorticity are consistent with the occurrence of chemical depletion.
