A method for real-time profiling of organic trace gases in the planetary boundary layer
Institut of Ion Physics and Applied Physics, University of Innsbruck, Innsbruck, Austria
Abstract. A method for real time profiling of volatile organic compounds (VOCs) was developed combining the advantages of a tethered balloon as a research platform and of proton transfer reaction mass spectrometry (PTR-MS) as an analytical technique for fast and highly sensitive VOC measurements. A 200 m Teflon tube was used to draw sampling air from a tethered aerodynamic balloon to the PTR-MS instrument. Potential positive and negative VOC artifacts of the inlet line were characterized in the laboratory and in the field and were found to be insignificant for most compounds. The method was successfully deployed during a winter field campaign to determine the small scale spatial and temporal pattern of air pollutants under winter inversion conditions.
