Summary
Over a period of 12 years, the lower tropospheric content of radionuclides beryllium 7, phosphorus 32, and phosphorus 33 has been measured at a mountain observatory in the Bavarian Alps. These nuclides are generated by cosmic radiation, mainly in the stratosphere. To control the effect of atmospheric nuclear explosions, the heavy metal fallout was determined. Production of these radionuclides is almost independent of solar activity, the influx into the troposphere is subject to this influence. In the exchange between stratosphere and troposphere periodicities are shown that depart from the annual variation. The effect of stratospheric air on the ozone content of the lower troposphere is investigated. The different half-lives of the radionuclides allow an assessment of the stratospheric residence times.
Zusammenfassung
Über einen Zeitraum von 12 Jahren wurde an einer Bergstation in den Bayerischen Alpen der Gehalt der unteren Troposphäre an den Radionukliden Beryllium 7 Bowie Phosphor 32 und Phosphor 33 gemessen. Diese Radionuklide werden durch die kosmische Strahlung insbesondere in der Stratosphäre erzeugt. Zur Kontrolle des Einflusses der atmosphärischen Kernexplosionen wurde der Schwermetallfallout erfaßt. Die Produktion der Radionuklide ist nahezu unabhängig von der solaren Aktivität, der Zustrom in die Troposphäre ist diesem Einfluss unterworfen. Es zeigen sich im Austausch zwischen Stratosphäre und Troposphäre Periodizitäten, die von der Jahresvariation abweichen. Der Einfluss stratosphärischer Luft auf den Ozongehalt der unteren Troposphäre wird untersucht. Wegen der unterschiedlichen Halbwertszeiten der Radionuklide ist eine Abschätzung der stratosphärischen Aufenthaltszeiten möglich.
