CLASS 1 Atmospheric Monitoring Station – Jungfraujoch

Main content

Measurements at the ICOS-CH Atmospheric Monitoring Station "Jungfraujoch" are jointly organized by the High Altitude Research Stations Jungfraujoch & GornergratUniversity of Bern, the Swiss Federal Laboratories of Material Sciences & Technology (Empa), 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 Heidelberg)
  • meteorology (MeteoSwiss)
  • planetary boundary layer with ceilometer (planned for August 2014 at Kleine Scheidegg; MeteoSwiss)
  • 222Radon with two-filter dual loop alpha particle detection (University of Basel)
  • N2O with off-axis Integrated Cavity Output Spectroscopy (planned for Q3/Q4 2014; Empa)

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

Real-time greenhouse gas concentration mole fractions are directly available from the Jungfraujoch Atmospheric Monitoring Station: CO2, CH4 and CO mole fractions
