Description: Das Projekt "Long-Term Greenhouse Gas Budget of a Subalpine Coniferous Forest" wird/wurde gefördert durch: Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung. Es wird/wurde ausgeführt durch: Eidgenössische Technische Hochschule Zürich, Institut für Agrarwissenschaften, Departement Biologie.The interest to study impacts of climate change on the terrestrial biosphere, particularly on forests, has been ever increasing over the last decades, since forests are an integral part of the global climate system and at the same time provide many ecosystem services, i.e., direct and indirect benefits for people. However, rather recently the need to quantify a whole suite of greenhouse gases (GHG), namely H2O, CO2, CH4 and N2O, was recognized. In a European effort to establish a unique network of top-level ecosystem GHG flux sites (ESFRI project ICOS; International Carbon Observation System), the main interest for the Swiss participation is focusing on the role of high mountain ecosystems in the continental GHG budget. To maximize synergies with already existing infrastructure and long-term research efforts in the subalpine zone of Switzerland, we propose to extend the on-going CO2, CH4 and H2O vapor flux measurements at Davos, Switzerland and participate in this European effort to establish the ICOS network. Our goal is to establish cutting-edge eddy covariance flux measurements of climatically relevant GHGs. With the R'Equip proposal, we will be able to add a research site to ICOS which is unique in three aspects, in its high elevation location (at 1670 m), in its flux measurement history (since 1997) and in its broad range of on-going auxiliary measurements (soil, vegetation, air pollutants). The study site Davos is a long-term site (since 1997) of the Grassland Sciences group at ETH as well as the designated Swiss primary ecosystem site of ICOS, supported by WSL and EMPA as well as FOEN and SBF. Our research is embedded in the Swiss efforts to assess GHG fluxes and land surface-atmosphere feedbacks (e.g., SwissFluxNet, C2SM, NCCR Climate, CCES-Maiolica) as well as in international efforts (e.g., CarboEurope IP, GHG-Europe, Carbo-Extreme, ICOS, FluxNet), providing relevant background information on GHG budgets of different land use types and thus the basis for post-Kyoto negotiations and sustainable land use. Thus, our objectives are to quantify CO2, H2O vapor, CH4 and N2O fluxes at the ecosystem level continuously using state-of-the art infra-red laser absorption spectrometers, enabling us (1) to test hypotheses on the magnitude of such fluxes of a forest (rarely tested for CH4 and N2O despite first reports on such fluxes and soil N2O sink capacity), (2) to determine forest responses to climatic (extreme) events, and (3) to better understand soil and ecosystem CO2 fluxes for the long-term GHG balance of a subalpine forest to ensure sustainable use of natural resources for climate protection AND wood production.
