Summary
Using hourly ozone concentration data from Zugspitze Observatory, of the Institute for Atmospheric Environmental Research, Garmisch-Partenkirchen, Germany, it is shown that under a propitious superposition of stratospheric and tropospheric flow patterns U.S. Federal maximum ozone standards of 80 ppb can occasionally be exceeded by a factor of two or more in the lower troposphere. Further dilution of these concentrations has to be expected by mixing processes in the planetary boundary layer.
Zusammenfassung
Stündliche Ozonkonzentrationswerte vom Zugspitzobservatorium des Institutes für Atmosphärische Umweltforschung, Garmisch-Partenkirchen, Bundesrepublik Deutschland, zeigten, daß bei einer günstigen Überlagerung von stratosphärischen und troposphärischen Strömungsfeldern die in den USA vorgeschriebene, einstündige Maximalkonzentration von 80 ppb unter Umständen um mehr als einen Faktor 2 in der unteren Troposphäre überschritten werden kann. Eine weitere Verdünnung dieser Konzentrationen kann durch die Mischungsprozesse in der planetaren Grenzschicht erwartet werden.
