Goethe-University Frankfurt/Main, Germany Institute of Environmental Systems Research, University Osnabrück, Germany Environment Monitoring Center, Orenburg State University, Russia Volatile organic compounds (VOCs) were analyzed in air and snow samples at the Jungfraujoch high alpine research station in Switzerland as part of CLACE 5 (CLoud and Aerosol Characterization Experiment) during February/March 2006. The fluxes of individual compounds in ambient air were calculated from gas phase concentrations and wind speed. The highest flux values were observed for the aromatic hydrocarbons benzene (14.3 μg m^−2s^−1), 1,3,5-trimethylbenzene (5.27 μg m^−2s^−1), toluene (4.40 μg m^−2s^−1), and the aliphatic hydrocarbons i-butane (7.87 μg m^−2s^−1), i-pentane (3.61 μg m^−2s^−1) and n-butane (3.23 μg m^−2s^−1). The fluxes were used to calculate the efficiency of removal of VOCs by snow, and the effect of temperature on removal efficiency. The removal efficiency was calculated at – 24°C (−13.7°C) and ranged from 37% (35%) for o-xylene to 93% (63%) for i-pentane. The distribution coefficients of VOCs between the air and snow phases were derived from published poly-parameter linear free energy relationship (pp-LFER) data, and compared with distribution coefficients obtained from the simultaneous measurements of VOC concentrations in air and snow at Jungfraujoch. The coefficients calculated from pp-LFER exceeded those values measured in the present study, which indicates more efficient snow scavenging of the VOCs investigated than suggested by theoretical predictions.
