Class 1 Atmosphere Station - Jungfraujoch

The Jungfraujoch station was awarded the status of an ICOS Class 1 station in May 2018 and is the highest measurement station in the ICOS network. Established in 1931, it has a long site history.

Measurements at Jungfraujoch station are jointly organized by the High Altitude Research Stations Jungfraujoch & GornergratUniversity of Bern, Swiss Federal Laboratories for Materials Science and Technology (Empa), Federal Office of Environment (FOEN) / National Air Pollution Monitoring Network (NABEL), Federal Office of Meteorology and Climatology MeteoSwiss, and the University of Basel

The ICOS relevant measurement programme at Jungfraujoch is organised as follows:

  • O2/N2 with paramagnetic sensor and fuel cell (University of Bern)
  • CO2, CH4, CO with Cavity Ringdown Spectroscopy (Empa)
  • 13C and 18O in CO2 with Quantum Cascade Laser Absorption Spectroscopy (Empa)
  • 14C (radiocarbon 14-day integrated samples; chemical absorption in sodium hydroxide solution and off-line analysis by radioactive counting; University of Bern and ICOS Radiocarbon Laboratory)
  • Meteorology (MeteoSwiss)
  • Planetary boundary layer with ceilometer (Kleine Scheidegg; MeteoSwiss)
  • 222Radon with two-filter dual loop alpha particle detection (University of Basel)
  • N2O with off-axis Integrated Cavity Output Spectroscopy (Empa)

Meteorological advection patterns at Jungfraujoch are routinely determined with back-trajectory analysis and a Lagrangian particle dispersion model calculations by Empa.

ICOScapes at Jungfraujoch

The #ICOScapes photo campaign raises awareness about climate change and greenhouse gas measurements in Europe through photographs and videos. The photos are taken by the famous nature and wildlife photographer Konsta Punkka during his visits to the stations.

ICOScapes has visited Jungfraujoch station in March 2018.
