Triple oxygen isotope composition of CO2 in the upper troposphere and stratosphere

Sampling altitude and coordinate, mole fraction of CO2 and other trace gases and the δ13C , δ17O , δ18O and ∆′17O of CO2 for StratoClim (Stratospheric and upper tropospheric processes for better climate predictions) and CARIBIC (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrument Container) samples. CARIBIC samples were collected using a Boeing 767 aircraft (LTU, Germany). The flights operated at typical commercial cruising altitude between 9 and 12 km, i.e. which is the upper troposphere–lower stratosphere region at higher latitudes and the upper-troposphere region in the mid-latitudes and tropics. StratoClim samples were collected with a high-altitude M55 Geophysica aircraft during two campaigns with a whole-air sampler of the Institutefor Marine and Atmospheric research Utrecht (IMAU), Utrecht University. All the isotope measurements were carried out atthe Institute for Marine and Atmospheric research Utrecht (IMAU), Utrecht University.
