A novel air sampling system was recently installed under the roof of the research station at Jungfraujoch. It will allow the automatic sampling of background air only during nighttime, when the station is mostly situated in the free troposphere, and thus avoid air masses influenced by more local fluxes that can rise until the station at daytime, especially during summer. Every two weeks, the air sampled in this way is transferred into a bag and transported back to the University of Bern for 14CH4 and 14CO2 analyses. Picture: DCBP/University of Bern
