Since 2004, atmospheric carbon dioxide (CO2) is being measured at the High Altitude Research Station Jungfraujoch by the division of Climate and Environmental Physics at the University of Bern (KUP) using a nondispersive infrared gas analyzer (NDIR)

We present results from an intercomparison program of CO2, δ(O2/N2) and δ13CO2 measurements from atmospheric flask samples. Flask samples are collected on a bi-weekly basis at the High Altitude Research Station Jungfraujoch in Switzerland for three

High-resolution δ13C measurements on ancient air extracted from less than 10 cm3 of ice

Autor: Leuenberger, M. C., Eyer, M., Nyfeler, P., Stauffer, B., Stocker, T. F.

Publikováno v: Tellus B; Vol 55, No 2 (2003)

A new method for δ13C analysis of very small air amounts of less than 0.5 cm3 STP was developed. This corresponds to less than 10 g of ice. It is based on the needle-crasher technique, which is routinely used for CO2 concentration measurements by in
