Abstract

Ten electrochemical concentration cell (ECC) ozonesondes were successfully flown at the Jet Propulsion Laboratory’s Table Mountain Facility during the Stratospheric Ozone Intercomparison Campaign (STOIC) conducted July 19 to August 2, 1989. Umkehr observations were made with a Dobson spectrophotometer during most mornings and afternoons. Ozone measurements were conducted primarily to assess the performance of lidar and microwave instrumentation destined for use in the planned station Network for Detection of Stratospheric Change (NDSC). Because the lidar and microwave are remote ozone measurement techniques, it was of interest to compare data obtained with these instruments with data from balloon-borne ECC ozonesondes that measure ozone directly by counting ozone molecules during balloon ascent. While most of the balloon soundings reached altitudes of 30-34 km, ozone measurements to about 39 km were obtained for two of the soundings.
