Abstract

Dry flux and dry deposition velocity of nitric oxide, sulfur dioxide and ozone were measured by the gradient method during the TRACT campaign in Rhine valley, Germany, above a surface covered by short vegetation. Eddy diffusivity was calculated by means of Monin-Obukhov's similarity theory. Calculated dry deposition velocities for ozone and sulfur dioxide were 0.05-0.07 and 0.19-0.20 cms-1 in stable and unstable cases, respectively. In the case of nitric oxide emission was observed in daytime, probably reflecting bacterial production.
