Abstract

The Canadian Atmospheric Environment Service (AES) operated a Brewer ozone spectrophotometer during the Stratospheric Ozone Intercomparison Campaign (STOIC) at Table Mountain Observatory from July 19 to August 2, 1989. Direct sun measurements of total column ozone and measurements of the ozone profile using the umkehr technique were made throughout the 2 weeks of the intercomparison. Results of the total ozone measurements made during the intercomparison are presented herein. Results of the umkehr measurements are given by McElroy and Kerr, this issue.
