AB: Long term observations are an indispensable pre-requisite to improve our knowledge of the complex biosphere- hydrosphere-atmosphere (BHA)-interactions and to detect and analyze the impact of Global Change parameters on these interactions as well as to develop, improve and validate BHA model systems. As an integral part of the Helmholtz initiative TERENO to establish/upgrade and equip terrestrial observatories for long term observations (> 10 years) on the effects of Global Change on complex terrestrial ecosystems, an observatory "Alpine Upland", operated jointly by the research centers FZK (Forschungszentrum Karlsruhe) and GSF (National Research Center for Environment and Health) is established. The central objectives of the scientific work performed by Forschungszentrum Karlsruhe within this observatory are: Characterization and quantification of changes of the (a) coupled C-/N-cycles and C-/N-storage (b)biosphere-atmosphere exchange (trace gases/energy flux/albedo) (c)vegetation and microbial biodiversity and of the temporal dynamics of matter- turnover and –exchange coupled to this change in biodiversity (d)terrestrial hydrology (alpine water budget, precipitation variability, extreme hydrometeorological events, seapage water quality/quantity, water retention capacity) in important climate- and use-sensitive ecosystem types within the pre-alpine region (e.g. alpine meadows, forests) under changing conditions of climate, management and nutrient deposition (atmospheric N-input). Besides upgrading of the already existing long term observation stations in the pre-alpine region ("The Höglwald Forest" (FZK) and the agricultural long term observation station "Scheyern" (for details see separate contribution of GSF) FZK will establish a "Climate-Feedback Observatory" at which the effects of predicted future changes in temperature and precipitation amount/distribution within the pre-alpine region on the complex BHA interactions will be studied applying a long term in-situ simulation experiment. For this a lysimeter network will be realized in which soil monoliths are transplanted along the existing natural gradient in temperature and precipitation within the alpine region. Details of this experimental approach will be presented.
