Abstract

Continuous Assessment of Vertical Fluxes of Trace Gases above a Rape Field A contribution to subproject BIATEX-2 C Scholz-Seidel and U. Dammgen Federal Agricultural Research Centre Braunschweig- Volkenrode, Institute for Agroecology, Bundesallee 50, 38116 Braunschweig, Germany The institute's main task is the determination of flux densities of matter and energy between atmosphere and agricultural land. The fluxes of airborne nutrients as well as ozone are of particular importance. Micrometeorological measurements of vertical flux densities and concentrations of trace gases and airborne nutrients have been performed at the Hasenholz field site (eastern Brandenburg, 52*33' N 14*01' E, 87 m a.s.L, approx. 50 km east of Berlin) using conventional instrumentation as far as possible, since 1996.
