AB: In the frame of the Schneefernerhaus Aerosol \& Reactive Nitrogen Experiment (SCAVEX) a Proton-Transfer-Reaction Mass Spectrometer was installed on the Environmental Research Station Schneefernerhaus (47.$42\deg$N, 10.$99\deg$E, 2650 m a.s.l.). The Schneefernerhaus is situated about 300 m below the peak of the Zugspitze in the German Alps. From 28th October 2002 to 12th March 2003 the remotely operated PTR-MS instrument measured a series of volatile organic compounds (VOCs) including oxygenates (methanol, acetaldehyde, acetone, methyl ethyl ketone), aromatics (benzene, toluene, alkyl substituted benzenes) and the biomass burning tracer acetonitrile. PTR-MS measurements on high mountain sites can be used to identify air masses with very different chemical characteristics, which have originated in the planetary boundary layer or have undergone long-range transport in the free troposphere. First results will be presented in this paper.
