Vertical Distribution and Variability of Ozone During July 1999 Over Andenes, NorwayOzonesonde measurements of the polar atmosphere obtained at Andenes, Norway during July 1999 showed unusual characteristics when compared with mid- or low-latitude ozone profiles. A minimum of two ozonesondes each day were released, one in late afternoon and one in early evening. A very well-defined ledge in the ozone profile corresponding to the tropopause appears to form as a result of transport. The ozone amount increases four to five times, from about 30 nb at the tropopause to 120 nb at a pressure about 10-20 hPa lower. The typical peak ozone value, although at a higher altitude than the ledge, appears at a much lower pressure (approx. 140 hPa) than found in midor low-latitudes (approx. 18-25 hPa), Total column ozone amounts are consistently higher than 300 DU. Analysis of the variation with regard to wind conditions will be discussed.
