Abstract

Irnmission and dry deposition of the trace gases Og and SO^ downwind of a main industrial region in Eastern Germany G. Spindler, W. Rolle, D. Theiss Institut Troposphdrenforschung e. V., Permoserstr. 15, D-04303 Leipzig, Germany ABSTRACT In this paper we present a short description of the measuring station near by the small village of Melpitz. Results of continuous measurement of the immission of SO^ Og, NO2 and NO and some results of the calculation of deposition velocities and fluxes for SC>2 and Og by the gradient technique are shown. The deposition velocities vary in the range from 0.03 to 0.16 cms"^ for SC>2 and 0.19 to 0.28 cms"^ for Og by night and in the range from 0.19 to 0.31 for SC>2 and 0.24 to 0.42 for Og. in the daytime Deposition velocities and fluxes are influenced by daytime and by the state of vegetation noticeable.
