Abstract
The paper gives a survey of the concepts, the methods and the measuring devices currently used to determine the dry deposition and emission of trace gases. Furthermore, problems inherent in these methods are pointed out and discussed. A short description of the essential micrometeorological measurements to determine fluxes for different compounds and to qualify errors is given, too. The so-called direct flux method for basic research as well as the progress in the development of accumulation methods are explained. To assess area-averaged mean values of dry deposition, an extensive explanation of the inferential method being used to estimate the dry deposition of inert and reactive trace gases is given.
