CO2 Isotopic Composition in the Upper Troposphere: the Project CARIBIC
Manuscript describes the project CARIBIC (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrument Container) and its approach of air sampling and CO2 isotope measurements by using a commercial aircraft (flights at ~ 10 km) as observational platform. In particular the paper focuses on possible sampling artefacts, on the troposphere-stratosphere mixing, effects which can specifically modify CO2 isotope composition and gives examples of CO2 isotope composition in the upper troposphere. The results to be presented in the manuscript have been obtained earlier, by measurements done at the Max Planck Institute for Chemistry, Mainz, Germany.
