Lidar observations of stratospheric ozone made at Eureka (80.0°N, 86.42°W) 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.
