Integrated Carbon Observation System (ICOS) ecosystem network: current state and future perspectives

Abstract : Atmospheric concentrations of greenhouse gases (GHG) such as carbon dioxide (CO2) and methane (CH4) are increasing due to emissions related to human activity, affecting the global climate. Natural sinks remove a fraction of the GHG anthropogenic excess at the global level. The characterization of greenhouse gases atmospheric burden and fluxes, both anthropogenic and natural, are needed at the global and regional scale, making use of all available information in an integrated framework. The Integrated Carbon Observation System (ICOS) research infrastructure will address this issue by providing the community with systematic measurements of a suite of atmospheric, terrestrial ecosystem and oceanic measurements. The ecosystem network comprises three station classes, for which variables are collected with different intensity. These stations are well distributed among the major European ecosystem types and cover most climatic zones in Europe. The Ecosystem Thematic Center (ETC) is coordinating the ICOS ecosystem network providing assistance with instruments and methods, testing and developing new measurement techniques and associated processing algorithms; also ensuring a high level of data standardization, uncertainty analysis and database services in coordination with the ICOS carbon portal. The ETC is also coordinating the drafting of the protocols describing in detail how measurements will be collected at all ecosystem stations, in order to guarantee inter comparability. This is done in close collaboration with experts in the field and with the other existing ecological and meteorological networks (NEON, Ameriflux, ICP –forests, MWO, TERN, …). This presentation will focus on the current state of the ICOS ecosystem network, on the data products and the potential user community.
