The high-altitude research station Jungfraujoch hosts a large number of instruments continuously measuring atmospheric concentrations of gases and particles emitted (mainly) from land surfaces. As a continental station, Jungfraujoch is influenced to changing degrees by local and more remote emission sources on diurnal, synoptic, and seasonal time scales. For interpreting atmospheric concentration records of gases and particles measured on site it is important to distinguish air masses influenced by local sources from air masses with a composition representative of the larger region, or of the northern hemisphere. A range of methods is applied to this end, including the NOy/CO ratio, time of day filters, meteorological/synoptic filters, trajectory analyses, and others. With our project we aim to contribute to a reliable and straightforward identification of “near baseline” conditions at Jungfraujoch through continuous precise measurement of radon-222 concentrations.
