TI: Micrometeorological Influences on Mass Transfer of BVOC?s at the Canopy Atmosphere Interface
AU: * Dlugi, R
EM: rdlugi@gmx.de
AF: AAP - Dlugi, Gernotstr. 11, Munich, D-80804 Germany
AB: The interactions between micrometeorological, plant physiological, hydrobiological and chemical processes on the net gas fluxes of BVOC's into the atmosphere on the stand scale from different field experiments (ECHO 2002, 2003; BEMA 1993-1997) are analyzed. Terms of the balance equations for micrometeorological and scalar quantities up to the third moment are determined from measurements. The influences of advection, convection and turbulence and the role of hydrological conditions on mass budgets will be discussed. In addition, the influence of the water status on mixing time scales and chemical reaction time scales will be analyzed.
