✦ Synopsis
One of the main goals of the 7-year winter precipitation field study on Mt. Rigi (central Switzerland) was a better understanding of the mechanisms leading to the wet removal of aerosol particles from the atmosphere. A critical review of the main below-cloud scavenging results of this event-oriented multidisciplinary project is given. The Mt. Rigi results are compared with a theoretical model applied to experimentally determined initial and boundary conditions and with literature reports on similar field studies. For submicron particles significant discrepancies have been found between experiment and theory, our measurements showing scavenging coefficients 20 to 40 times higher on average than model predictions. An attempt is made to explain the differences resulting from these two different approaches. There is some evidence that this may arise partly as a result of humidity effects, but other influences are discussed as well.
