Ion Deposition Due To Fog Water Interception at High Elevations

  • G. Kroll

The ion deposition via fog interception has been estimated using a one dimensional cloud droplet deposition model and measured concentrations of trace constituents. The model uses observed meteorological data as input parameters. The fog deposition becomes important for mountain regions which rise more than 600 m above the surrounding flat terrain. The ion deposition via fog becomes as important or more important than wet deposition above that heights. The regional variation of ion deposition via fog is much higher than that of precipitation due to large variations in the fog respectively cloud water composition. Although the present assessment is still relatively uncertain, we can conclude that a cut of extreme concentrations reduces the ion deposition over proportionally.
