In the ongoing carbon balance field campaign at Jungfraujoch, researchers from several European countries aim for a better characterization of carbonaceous species in the free troposphere, which may help to reduce uncertainties in climate models. Various mass spectrometers, gas chromatographs and total carbon analyzers have been installed in the Sphinx observatory to measure the atmospheric gas and particle phase composition.
