Atmospheric ozone at the South Pole during 1986
- National Oceanic and Atmospheric Administration, Boulder, CO (USA)
The program of ozone research in Antarctica carried out by the National Oceanic and Atmospheric Administration's Geophysical Monitoring for Climatic Change Program (GMCC) is part of a comprehensive program of atmospheric trace gas and particle measurements made by GMCC at the South Pole and numerous locations around the world. Based on 22 years of measurements from 1964-1985 of the atmospheric total column ozone amount, Komhyr, Grass, and Leonard (1986) reported total ozone at the South Pole in 1985 to be roughly 20 percent lower on an annual basis than values present in the mid-1960s; the decrease in austral spring values was considerably larger. It was also shown that sine 1979, there has been a marked retardation in the time of the springtime stratospheric warming over Antarctica and the accompanying influx of ozone. In 1986, an ozone vertical profile measurement program was added to the long-term program of total column and in situ surface-based ozone measurements. Fifty-one vertical profiles were obtained throughout the year using light-weight, balloonborne electrochemical concentration cell (ECC) ozonesondes. In addition to providing detailed ozone profiles to altitudes of 30-35 kilometers, the ozonesconde data were integrated to give a clearer picture of the seasonal march of total ozone. Results are given.
