Abstract
Dry flux and dry deposition velocity of nitric oxide, sulfur dioxide a nd ozone were measured by the gradient method during the TRACT campaig n in Rhine valley, Germany, above a surface covered by short vegetatio n. Eddy diffusivity was calculated by means of Monin-Obukhov's similar ity theory. Calculated dry deposition velocities for ozone and sulfur dioxide were 0.05-0.07 and 0.19-0.20 cm s(-1) in stable and unstable c ases, respectively. In the case of nitric oxide emission was observed in daytime, probably reflecting bacterial production. (C) 1998 Elsevie r Science Ltd. All rights reserved.
