Central objectives were to generate extensive data sets on air quality including trends and pollutant source-receptor relationships, to investigate the interaction of atmospheric const

From a scientific point of view, in particular with regard to the objective of measuring fluxes into and within the ecosystem, including their balances, each component has to be quantified, i.e. it is indispensable to separate as far as possible wet and dry deposition.

Methodology for the Determination of Atmospheric Deposition and of Fluxes within the Ecosystem Compss are quite different and depend strongly on the attendant conditions, the constituent to be measured and the quality of the available technique. In any case, the quantification of dry deposition is much more difficult and subject to errors as compared to that of wet deposition.
