Abstract
The trace substance deposition to coniferous forests via cloud interception at higher elevations is assessed. This is achieved in three steps: (1) The deposition fluxes of cloud water are calculated according to the deposition model of Lovett using observed meteorological data. (2) At various mountain sites cloud water is collected and analyzed for selected trace substances. (3) By a certain procedure the deposition fluxes are combined with the measured concentrations in order to estimate the deposition of trace substances. Although large uncertainties have still to be overcome, the results show that at high altitudes the input of trace substances to coniferous ecosystems due to interception of cloud droplets can be as high or even higher than the deposition by rain. Especially the nitrate deposition via cloud interception is higher at most sites than the sulfate deposition whereas for wet deposition the sulfate input is higher than the nitrate input.
