Abstract: | Quartz-UV occultation measurements by the satellite Interkosmos-16 have been used to calculate ozone densities at altitudes between 55 and 75 km for the period July 27 – October 28 of 1976. Although the densities agree quite well with the Krueger-Minzner-model below 65 km distinct seasonal-latitudinal variations have been found. During July and August latitudinal variations are more pronounced than in September and October with a slight maximum shifting from 5° S in July to 30 – 40° S in September. A comparison of different height levels shows a decreasing latitudinal variation for increasing altitude during July and August and rather modest variations for September and October. |
