Abstract
During winter/spring 96/97 ozone levels over the Eureka NDSC observato ry (80 degrees N,86 degrees W) were measured using a lidar, sondes, an d a Brewer spectrophotometer. Column ClO measurements were also made u sing an FTIR system. Measurements show that lower stratospheric ozone mixing ratios decreased rapidly between mid-February and late-March th ough the ozone mixing ratio losses appear to have been less than for t he 95/96 season. Elevated column amounts of ClO were found to be prese nt over Eureka until late March.
