Comparison between real time and flask measurements of atmospheric O2 and CO2 performed at the High Altitude Research Station Jungfraujoch, Switzerland.

First real time CO2 and O2 measurements on the High Altitude Research Station Jungfraujoch (Switzerland) are compared with corresponding flasks samples. Whereas CO2 measurements show a good agreement, O2 compares only moderately. Real time O2 measurements are performed using two different methods, i.

Measurements and trend analysis of O2, CO2 and delta13C of CO2 from the high altitude research station Junfgraujoch, Switzerland--a comparison with the observations from the remote site Puy de Dôme, France.

Atmospheric O2 and CO2 flask measurements from the high altitude research station Jungfraujoch, Switzerland, and from the observatory at Puy de Dôme, France, are presented. Additionally, the Jungfraujoch delta13C record of CO2 is discussed. The observations on flask samples collected at the Jungfraujoch station show, since 2003, an enhancement of the oxygen trend which amounts to about 45 per meg/year with a corresponding CO2 increase of around 2.
