  • Statistical properties of random CO2 flux measurement uncertainty inferred from model residuals (2008)

    Authors:Richardson, A.D.; Mahecha, M.D.; Falge, E.; Kattge, J.; Moffat, A.M.; Papale, D.; Reichstein, M.; Stauch, V.J.; Braswell, B.H.; Churkina, G.; Kruijt, B.; Hollinger, D.Y.
    In:Agricultural and Forest Meteorology, 148(1), 38 - 50. ISSN 0168-1923.

    Abstract:

    Information about the uncertainties associated with eddy covariance measurements of surface-atmosphere CO2 exchange is needed for data assimilation and inverse analyses to estimate model parameters, validation of ecosystem models against flux data, as well as multi-site synthesis activities (e.g., r

  • Nocturnal accumulation of CO2 underneath a tropical forest canopy along a tropographical gradient (2008)

    Authors:Araújo, de A.C.; Kruijt, B.; Nobre, A.D.; Dolman, A.J.; Waterloo, M.J.; Moors, E.J.; Souza, de J.
    In:Ecological Applications, 18(6), 1406 - 1419. ISSN 1051-0761.

    Abstract:

    Flux measurements of carbon dioxide and water vapor above tropical rain forests are often difficult to interpret because the terrain is usually complex. This complexity induces heterogeneity in the surface but also affects lateral movement of carbon dioxide (CO2) not readily detected by the eddy cov

  • Implications of CO2 pooling on δ13C of ecosystem respiration and leaves in Amazonian forest (2008)Open access

    Authors:Araujo, de A.C.; Ometto, J.P.H.B.; Dolman, A.J.; Kruijt, B.; Waterloo, M.J.; Ehleringer, J.R.
    In:Biogeosciences, 5(3), 779 - 795. ISSN 1726-4170.

    Abstract:

    The carbon isotope of a leaf (δ13Cleaf) is generally more negative in riparian zones than in areas with low soil moisture content or rainfall input. In Central Amazonia, the small-scale topography is composed of plateaus and valleys, with plateaus generally having a lower soil moisture status than t

  • Climate change impacts on Developing Countries - EU Accountability (2007)Open access

    Authors:Ludwig, F.; Terwisscha Van Scheltinga, C.T.H.M.; Verhagen, J.; Kruijt, B.; Ierland, van E.C.; Dellink, R.B.; Bruin, de K.; Bruin, de K.C.; Kabat, P.

  • Isoprene and monoterpene fluxes from Central Amazonian rainforest inferred from tower-based and airborne measurements, and implications on the atmospheric chemistry and the local carbon budget (2007)Open access

    Authors:Kuhn, U.; Andreae, M.O.; Ammann, C.; Araújo, A.C.; Brancaleoni, E.; Ciccioli, P.; Dindorf, T.; Frattoni, M.; Gatti, L.V.; Ganzeveld, L.N.; Kruijt, B.; Lelieveld, J.; Lloyd, J.; Meixner, F.X.; Nobre, A.D.; Pöschl, U.; Spirig, C.; Stefani, P.; Thielmann, A.; Valentini, R.; Kesselmeier, J.
    In:Atmospheric Chemistry and Physics, 7(11), 2855 - 2879. ISSN 1680-7316.

    Abstract:

    We estimated the isoprene and monoterpene source strengths of a pristine tropical forest north of Manaus in the central Amazon Basin using three different micrometeorological flux measurement approaches. During the early dry season campaign of the Cooperative LBA Airborne Regional Experiment (LBA-CL

  • An airborne regional carbon balance for Central Amazonia (2007)Open access

    Authors:Lloyd, J.; Kolle, O.; Fritsch, H.; Freitas, de S.R.; Silva Dias, M.A.F.; Artaxo, P.; Nobre, A.D.; Araújo, de A.C.; Kruijt, B.; Sogacheva, L.; Fisch, G.; Thielmann, A.; Kuhn, U.; Andreae, M.O.
    In:Biogeosciences, 4(5), 759 - 768. ISSN 1726-4170.

    Abstract:

    We obtained regional estimates of surface CO2 exchange rates using atmospheric boundary layer budgeting techniques above tropical forest near Manaus, Brazil. Comparisons were made with simultaneous measurements from two eddy covariance towers below. Although there was good agreement for daytime meas

  • CO2 balance of boreal, temperate, and tropical forests (2007)

    Authors:Luyssaert, S.; Inglima, I.; Jungs, M.; Richardson, A.; Reichsteins, M.; Papale, D.; Piao, S.L.; Schulzes, E.D.; Wingate, L.; Matteucci, G.; Aragaoss, L.; Aubinet, M.; Beers, van C.; Bernhofer, C.; Black, K.G.; Bonal, D.; Bonnefonds, J.M.; Chambers, J.; Ciais, P.; Cook, B.; Davis, K.J.; Dolman, A.J.; Gielen, B.; Goulden, M.; Grace, J.; Granier, A.; Grelle, A.; Griffis, T.; Grunwald, T.; Guidolotti, G.; Hanson, P.J.; Harding, R.; Hollinger, D.Y.; Hutyra, L.R.; Kolari, P.; Kruijt, B.; Kutsch, W.; Lagergren, F.; Laurila, T.; Law, B.E.; Le Maire, G.; Lindroth, A.; Loustau, D.; Malhi, Y.; Mateus, J.; Migliavacca, M.; Misson, L.; Montagnani, L.; Moncrief, J.; Moors, E.J.; Munger, J.W.; Nikinmaa, E.; Ollinger, S.V.; Pita, G.; Rebmann, C.; Roupsard, O.; Saigusa, N.; Sanz, M.J.; Seufert, G.; Sierra, C.; Smith, M.; Tang, J.; Valentini, R.; Vesala, T.; Janssens, I.A.
    In:Global Change Biology, 13(12), 2509 - 2537. ISSN 1354-1013.

    Abstract:

    Terrestrial ecosystems sequester 2.1 Pg of atmospheric carbon annually. A large amount of the terrestrial sink is realized by forests. However, considerable uncertainties remain regarding the fate of this carbon over both short and long timescales. Relevant data to address these uncertainties are be
