Field Trip


5 July

07:00 to 20:40 (back in Lausanne)





Jungfraujoch: Insights Out of Thin Air

Meeting point: Parking Lausanne Bellerive at 07:00 (IMPORTANT: this bus must leave at 07:15 sharp in order to catch the connecting train to Jungfraujoch. DO NOT BE LATE!!!!!)

Transport: bus and train (cog railway to Jungfraujoch)

Number of participants: 35

Registration fee: CHF 17 (transport and lunch included)

Details: Wear good shoes and warm clothes; we will be at around 3700 m.a.s.l. (11,371 feet above sea level). Bring enough drinks with you (at least 0.5 liter) to drink on the way up.

Risks: High altitude sickness. Medical recommendations for high altitude excursions

(leaflet) here.

Organizer and sponsor: High Altitude Research Station on Jungfraujoch and Swiss Academy of Sciences

Contact: Manuela Di Giulio (


This full-day excursion starts with a spectacular train ride through a frosty world of tunnels, precipices and glaciers up to the High Altitude Research Station Jungfraujoch and the Sphinx Observatory at 3570 m.a.s.l. (11,716 feet above sea level). The tour through the research laboratories features measuring systems for atmospheric trace gases, aerosol parameters to monitor air quality, sources of pollutants and climate change, and to investigate snow and ice. The station’s project leaders will present ongoing research and answer specific questions.

This trip offers a unique opportunity to visit the highest research station in Europe accessible by public transport. Thanks to its location above the planetary boundary layer, the High Altitude Research Station on Jungfraujoch is a key station in the World Meteorological Organization’s (WMO) Global Atmosphere Watch (GAW) and an important link in numerous other national and international networks. Operating in a locally unpolluted atmosphere, it provides unique reference data on the state and evolution of the chemical composition and aerosol content of the Earth’s atmosphere.
