Abstract. Lidar observations of stratospheric ozone made at Eureka (80.0N, 86.42W) during the 95/96 winter show substantial declines in ozone mixing ratios. Reductions in ozone levels of up to 40 % between the 410 K and 580 K isentropic levels were observed between mid-January and mid-March. The correlation of the ozone data with potential vorticity and concurrent lidar observations of stratospheric aerosol is consistent with the claim that significant chemical depletion did occur.
