Abstract

This is the final report of a project, which was funded by the German Federal Ministry for Research and Technology (BMFT), file No. 01 V0Z15 6, and was conducted from 1 March, 1990 until 30 June, 1993. It was the goal of the project to record zenith column amounts (ZCA`s) of trace gases, which are relevant to ozone chemistry and to the development of ozone sinks in the Arctic. Above all, the contribution of dynamic and chemical processes was to be clarified as well as the question whether parallels can be drawn between the chemistry of the Arctic and the Antarctic stratosphere. The equipment used were two Fourier transform spectrometers (FTS). They allow the IR spectrum of direct sunlight to be measured which is attenuated selectively by the atmospheric trace gases, dependent on their concentrations. To be able to calculate the ZCA`s, synthetic spectra are fitted to the measured ones taking into account the measuring geometry, and by varying vertical profiles of the mixing ratios used to calculate the synthetic spectra. An advantage offered by this measuring technique is that the ZCA`s of many trace gases can be determined simultaneously in the same probed mass of air. (orig.) [Deutsch] Es  More>>

[Deutsch] Es handelt sich um den Schlussbericht eines vom BMFT gefoerderten Vorhabens, das unter dem Foerderkennzeichen 01 V0Z15 6 vom 01.03.1990 bis zum 30.06.1993 lief. Das Ziel des Vorhabens lag in der Erfassung von Saeulengehalten von Spurengasen, die fuer die Ozonchemie und fuer die Ausbildung von Ozonsenken in der Arktis relevant sind. Dabei sollte geklaert werden, welchen Anteil dynamische und chemische Prozesse haben und ob die Chemie der arktischen Stratosphaere Parallelen zu denjenigen in der Antarktis aufweist. Als Geraete wurden zwei Fourier-Transformationsspektrometer (FTS) eingesetzt, die das IR-Spektrum des direkten Sonnenlichts messen, das die atmosphaerischen Spurengase in Abhaengigkeit ihrer Konzentration selektiv schwaechen. Zur Berechnung der Saeulendichten werden synthetische Spektren unter Beruecksichtigung der Messgeometrie an die gemessenen angepasst und die zur Berechnung der synthetischen Spektren verwendeten vertikalen Profile der Mischungsverhaeltnisse in einem Least-squares-fit-Verfahren variiert. Ein Vorteil dieser Messtechnik ist, dass in derselben sondierten Luftmasse die Saeulengehalte vieler Spurengase simultan bestimmt werden koennen. (orig.)}
