TERENO International Conference 2014

International Conference 2014 from Observation to Prediction in Terrestrial Systems

29 September to 2 October 2014

Rheinische Friedrich-Wilhelms-Universität Bonn, Germany



TERENO (TERestrial ENvironmental Observatories)

TERENO observatory 'preAlpine'
HGF-Initiative TERENO

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.
For long term observations on the effects of Global Change on complex terrestrial ecosystems we establish an “preAlpine” observatory consisting of the long term agricultural monitoring site Scheyern (Helmholtz-Zentrum München), long term forest monitoring site 'Höglwald' and surrounding agricultural fields (Karlsruhe Institute of Technology) and the climate-feedback observatory 'Ammer catchment' (Karlsruhe Institute of Technology).



Micromet data from the TERENO Ammer catchment




Main long term objectives of the preAlpine-observatory are the characterization and quantification of climate change effects on:


biogeochemical processes:


  • changes of the coupled C-/N-cycles and C-/N-storage
  • biosphere-atmosphere exchange (trace gases, energy flux, albedo)
  • vegetation and microbial biodiversity and temporal dynamics of matter-turnover and -exchange coupled to changes in biodiversity

terrestrial hydrology:




    • alpine water balances and precipitation variability
    • hydrometeorological extreme events
    • water quality and retention capacity


    in prealpine ecosystems particularly sensitive to changes in climate, nutrient deposition and land use/management (wet grasslands/fens, forests and agricultural systems).


    Integration of the TERENO Longterm Observatory 'preAlpine' in current projects and networks


    In general, TERENO observatories are an open platform and intend to establish new and extend existing national and international scientific cooperations!

    Climate Feedback Station 'Ammer Catchment'

    TERENO Ammer Catchment

    A lysimeter network will be realized in which soil monoliths with grassland vegetation are transplanted along the existing natural gradient in temperature and precipitation within the alpine Ammer catchment.


    The following parameters will be determined and quantified:

    • Greenhouse gas (GHG) exchange
    • NO3- export
    • Water and Energy balance
    • Soil NO3-/NH4+ concentrations
    • Soil microbial biomass and soil microbial biodiversity
    • Vegetation (growth rate and biodiversity)


    The Climate Feedback Station 'Ammer Catchment' will be equipped with

    • Climate station
    • Micro rain radar (MRR2)
    • Eddy covariance system for quantification of energy balance and turbulent fluxes of CO2 and H2O
    • 36 lysimeters (volume c. 2 m3 each)
    • Greenhouse chamber system for determination of surface fluxes of N2O, CH4, CO2, and NOX at lysimeters
    • Photometer for quantification of nitrate export at two existing water gauges

    Long term forest monitoring site 'Höglwald'

    TERENO Hoeglwald
    TERENO: Agriculture-Forestry Interface

    The already existing and well equipped Long Term Ecological Forest Research site 'Höglwald' will be expanded by establishing an agricultural site in direct vicinity to the forest site. For investigation of the Biosphere-Hydrosphere-Atmosphere (BHA) interactions between agriculture and forest ecosystems the facilities of the long term monitoring site 'Höglwald' will be upgraded with advanced measuring equipment e.g.

    • Eddy covariance (EC) system for determination of energy balance and vertical fluxes of CO2 and H2O (net ecosystem exchange) at the agriculture site
    • Greenhouse gas chamber systems for determination of surface fluxes of N2O, CO2, CH4, and NOX,  at the agriculture site
    • Climate station
    • Tunable Diode Laser Absorption Spectrometer (TDLAS) for EC based NH3 measurements
    • TDLAS for EC based N2O measurements
    • Discharge water gauges (4) with autosamplers for monitoring the fluxes of N and C export
