Kiese, H. Papen, H. Kunstmann, K. Butterbach-Bahl, A. Marx, H.P. SchmidIMK-IFU Garmisch-Partenkirchen, GermanyIntroductionClimate change observations since 1860 show a dramatic temperature increase of around 2°C in the German Alps. Regional climate models simulate an additional warming of 2°C during the next 40 years, in combination with decreasing precipitation amounts, especially in summer time (~ -30%). This will affect the biosphere, gas exchange processes, energy balance, as well as the water cycle in this climate sensitive region. 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. Therefore, we establish a long term observatory in the alpine and pre-alpine upland in southern Bavaria, Germany, to observe the effects of Global Change on  complex terrestrial ecosystems. Within the Alpine upland, we cooperate with GSF who expand        the existing Observatory Scheyern, located north of Munich. The Observatory is part of the TERENO project, which consists in total of three long term observatories located all over Germany.  Main ObjectivesCharacterization and quantification of climate change effects on• changes of the coupled C-/N-cycles and C-/N-storage • biosphere-atmosphere exchange (trace gases/energy flux/albedo)• vegetation and microbial biodiversity and of the temporal dynamics of matter-turnover and – exchange coupled to this change in biodiversity• terrestrial hydrology (alpine water budget, precipitation variability,  extreme hydrometeorological events (floods/droughts), seepage water quality/quantity, water retention capacity)Agriculture – ForestInterface EC Tower:CO2, H2O, EnergybalanceGHG System:N2O, NOx, CO2, CH4Graswang~ 950 maslUnternogg~ 850 maslWeilheim~ 550 maslTemp-gradient~ 2.5 °CPrecipitation-gradient~ 500 mmObservatory Ammer-catchment: Climate Change Experiment Alpine RegionObservatory Höglwald: Agri – Forest Interface in the prealpine regionIn the Ammer-catchment, a lysimeter network , consisting of total 36 monoliths at three locations, will be realized.
