The dissertationfocuses on the biogeochemistry of the vegetation layer (canopy) and the interac-tions between physiological and environmental processes which afiect the climateand chemistry of the lower atmosphere. A main task is the quantiflcation ofvertical exchange of trace gases and energy with theoretical concepts consideringthe links and feedbacks between the partitioning of energy at the leaf surface,the uptake of CO , the emission of biogenic volatile organic compounds (VOC),2the dry deposition of ozone, the vertical transport within the canopy and theecosystem net exchange (vertical ?uxes).
