  • Measurements of trace constituents at the high Alpine backgroundstation Sonnblick : a contribution to the EUROTRAC subproject TOR
    Puxbaum, Hans ; Gomišček, Boštjan ; Radunsky, Klaus
    Within the mainframe program of TOR continous ozone measurements were performed at the SBO site at 3106 m a.s.l. The annual ozone average concentration for 1991 was 47 ppb. The seasonal trend shows a ... spring maximum in April-May and a summer maximum in the first half of July. During an intensive campaign in July and August measurements of elevational profiles of ▫$CO_3$▫ from the bottom of the valley (1600 m a.s.l.) to the SBO (3106 m a.s.l.) site and continous measurements of NO, ▫$NO_2$▫, ▫$NO_y$▫, ▫$J_{NO2}$▫, ▫$O_3$▫ and CO at the valley ground were performed. Additionally NMVOC, aldehydes, substances measured with the Denuder technique and ozone airborne measurements over two successive days completed the campaign. From the dynamic behaviour of the ozone profiles we concluded, that transport processes were the dominant factor for the fluctuation of ozone concentrations.
