  • The CO2 release and Oxygen uptake from Fossil Fuel Emission Estimate (COFFEE) dataset: effects from varying oxidative ratios

    Steinbach, J.; Gerbig, C.; Roedenbeck, C.; Karstens, U.; Minejima, C.; Mukai, H. (2011)
    Projects: EC | ICOS (211574)
    We present a global dataset of CO2 emissions and O2 uptake associated with the combustion of different fossil fuel types. To derive spatial and temporal patterns of oxygen uptake, we combined high-resolution CO2 emissions from the EDGAR (Emission Database for Global Atmospheric Research) inventory with country level information on oxidative ratios, based on fossil fuel consumption data from the UN energy statistics database. The results are hourly global maps with a spatial resolution of 1°&t...

    Implication of weekly and diurnal 14C calibration on hourly estimates of CO-based fossil fuel CO2 at a moderately polluted site in southwestern Germany

    Vogel, Felix R.; Hammer, Samuel; Steinhof, Axel; Kromer, Bernd; Levin, Ingeborg (2011)
    Projects: EC | ICOS (211574)
    A 7-year-long data set of integrated high-precision 14CO2 observations combined with occasional hourly 14CO2 flask data from the Heidelberg sampling site is presented. Heidelberg is located in the highly populated and industrialized upper Rhine valley in southwestern Germany. The 14CO2 data are used in combination with hourly carbon monoxide (CO) observations to estimate regional hourly fossil fuel CO2 (ΔFFCO2) mixing ratios. We investigate three different 14C calibration schemes to calculate...

    Can we evaluate a fine-grained emission model using high-resolution atmospheric transport modelling and regional fossil fuel CO2 observations?

    Vogel, Felix R.; Tiruchittampalam, Balendra; Theloke, Jochen; Kretschmer, Roberto; Gerbig, Christoph; Hammer, Samuel; Levin, Ingeborg (2013)
    Projects: EC | ICOS (211574)
    Quantifying carbon dioxide emissions from fossil fuel burning (FFCO2) is a crucial task to assess continental carbon fluxes and to track anthropogenic emissions changes in the future. In the present study, we investigate potentials and challenges when combining observational data with simulations using high-resolution atmospheric transport and emission modelling. These challenges concern, for example, erroneous vertical mixing or uncertainties in the disaggregation of national total emissions...

    Feasibility study of using a "travelling" CO<sub>2</sub> and CH<sub>4</sub> instrument to validate continuous in situ measurement stations

    S. Hammer; G. Konrad; A. T. Vermeulen; O. Laurent; M. Delmotte; A. Jordan; L. Hazan; S. Conil; I. Levin (2013)
    Projects: EC | ICOS (211574)
    In the course of the ICOS (Integrated Carbon Observation System) Demonstration Experiment a feasibility study on the usefulness of a travelling comparison instrument (TCI) was conducted in order to evaluate continuous atmospheric CO2 and CH4 measurements at two European stations. The aim of the TCI is to independently measure ambient air in parallel to the standard station instrumentation, thus providing a comprehensive comparison that includes the sample intake system, the instrument itself ...

    Atmospheric Delta (CO2)-C-14 trend in Western European background air from 2000 to 2012

    Levin, Ingeborg; Kromer, Bernd; Hammer, Samuel (2013)
    Projects: EC | ICOS (211574)
    Long-term measurements of atmospheric Δ14CO2 from two monitoring stations, one in the European Alps (Jungfraujoch, Switzerland) and the other in the Black Forest (Schauinsland, Germany), are presented. Both records show a steady decrease, changing from about 6‰ per year at the beginning of the century to only 3‰ per year on average in the last 4 yr. A significant seasonal variation of Δ14CO2 is observed at both sites with maxima during late summer and minima in late winter/early spring. While...

    On the potential of the ICOS atmospheric CO<sub>2</sub> measurement network for estimating the biogenic CO<sub>2</sub> budget of Europe

    N. Kadygrov; G. Broquet; F. Chevallier; L. Rivier; C. Gerbig; P. Ciais (2015)
    Projects: EC | ICOS (211574), EC | GEOCARBON (283080)
    We present a performance assessment of the European Integrated Carbon Observing System (ICOS) atmospheric network for constraining European biogenic CO2 fluxes (hereafter net ecosystem exchange, NEE). The performance of the network is assessed in terms of uncertainty in the fluxes, using a state-of-the-art mesoscale variational atmospheric inversion system assimilating hourly averages of atmospheric data to solve for NEE at 6 h and 0.5° resolution. The performance of the ICOS a...

    Automatic processing of atmospheric CO2 and CH4 mole fractions at the ICOS Atmosphere Thematic Centre

    Hazan, Lynn; Tarniewicz, Jérôme; Ramonet, Michel; Laurent, Olivier; Abbaris, Amara (2016)
    Projects: EC | ICOS-INWIRE (313169), EC | ICOS (211574)
    The Integrated Carbon Observation System Atmosphere Thematic Centre (ICOS ATC) automatically processes atmospheric greenhouse gases mole fractions of data coming from sites of the ICOS network. Daily transferred raw data files are automatically processed and archived. Data are stored in the ICOS atmospheric database, the backbone of the system, which has been developed with an emphasis on the traceability of the data processing. Many data products, updated daily, explore the da...

    Near Real Time Data Processing In ICOS RI

    Hellström, Margareta; Vermeulen, Alex; Mirzov, Oleg; Sabbatini, Simone; Vitale, Domenico; Papale, Dario; Tarniewicz, Jérôme; Hazan, Lynn; Rivier, Leonard; Jones, Steve D.; Pfeil, Benjamin; Johannessen, Truls (2016)
    Projects: EC | ENVRI PLUS (654182), EC | ICOS (211574)
    This paper describes the implementation of (near) real-time (NRT) data processing in the recently launched European environmental research infrastructure ICOS. NRT applications include handling of raw sensor data (including safe storage and quality control), processing and evaluation of greenhouse gas mixing ratios and exchange fluxes, and the provision of data to the RI’s user communities.

    Simulation of surface energy fluxes and stratification of a small boreal lake by a set of one-dimensional models

    Victor Stepanenko; Klaus D. Jöhnk; Ekaterina Machulskaya; Marjorie Perroud; Zack Subin; Annika Nordbo; Ivan Mammarella; Dmitri Mironov (2014)
    Projects: EC | ICOS (211574), EC | GHG EUROPE (244122)
    Five one-dimensional (1D) lake models were run for the open water season in 2006 for Lake Valkea-Kotinen (Finland) using on-lake measured meteorological forcing. The model results were validated using measurements of water temperature and of eddy covariance (EC) fluxes. The surface temperature is satisfactorily simulated by all models showing slight overestimation (by 0.1–1.1°C). Both sensible and latent heat fluxes are positively biased in respect to EC data, consistent with earlier studies....
