Abstract: The biosphere ploys a key role in the trace compound exchange between the earth's surface and the atmosphere. Due to their high emission rates and their high reactivities biogenic volatile organic compounds (BVOC) ore of paramount importance for oxidation processes in the atmosphere. In recent years, national and international integrated research efforts significantly improved our knowledge about oxidation pathways in particular in forest atmospheres, biochemical synthesis of isoprenoids, genetic and environmental control mechanisms, and emitted chemical compound pattern. Further, the spatial distribution of emission sources in landscapes and their hourly, daily, seasonal and annual variation has been studied in detail. This includes the development and continuous update of instruments, analytical methods as well as modelling approaches. But despite the great progress made in the post years still major gaps exist in particular on the emission of sesquiterpenes and oxygen-containing VOC from the biosphere. Further, our understanding of inside forest air chemistry is still very limited. In consequence, the future will bring up exiting new in sights in the complex reactive carbon turnover in the earth system linked to feedback processes resulting from climate and land use change.
