Comparison of wet deposition inputs via rain and fog interception at a high elevated forest site

Abstract

The absolute amounts of water and atmospheric trace subtances deposited to forests due to the interception of fog and cloud droplets are a function of meteorological parameters and geometrical structure of the vegetation surfaces. This report examines a simple method of determining interception deposition during isolated instances of high-density fog over long periods of time. The results indicate that fog interception is an important factor in the total input of trace elements into forest ecosystems. In forested subdued mountain areas with a high instance of fog, interception deposition can cause inputs of pollutants, containig specific elements, of up to 50 mg/m² per event.
