Journal ArticleDOI
Energy balance closure at FLUXNET sites
Kell B. Wilson,Allen H. Goldstein,Eva Falge,Marc Aubinet,Dennis D. Baldocchi,Paul Berbigier,Christian Bernhofer,Reinhart Ceulemans,Han Dolman,Christopher B. Field,Achim Grelle,A. Ibrom,Beverly E. Law,Andrew S. Kowalski,Tilden P. Meyers,John Moncrieff,Russell K. Monson,Walter C. Oechel,John Tenhunen,Riccardo Valentini,Shashi B. Verma +20 more
TL;DR: A comprehensive evaluation of energy balance closure is performed across 22 sites and 50 site-years in FLUXNET, a network of eddy covariance sites measuring long-term carbon and energy fluxes in contrasting ecosystems and climates as mentioned in this paper.
Book ChapterDOI
Estimates of the annual net carbon and water exchange of forests: the EUROFLUX methodology
Marc Aubinet,Achim Grelle,Andreas Ibrom,Üllar Rannik,John Moncrieff,Thomas Foken,Andrew S. Kowalski,Philippe H. Martin,Paul Berbigier,Christian Bernhofer,Robert Clement,Jan Elbers,André Granier,Thomas Grünwald,K. Morgenstern,Kim Pilegaard,Corinna Rebmann,W. Snijders,Riccardo Valentini,Timo Vesala +19 more
TL;DR: In this article, the authors have described the measurement system and the procedure followed for the computation of the fluxes and procedure of flux summation, including data gap filling strategy, night flux corrections and error estimation.
Journal ArticleDOI
Respiration as the main determinant of carbon balance in European forests
Riccardo Valentini,Giorgio Matteucci,A. J. Dolman,Ernst Detlef Schulze,Corinna Rebmann,Eddy Moors,A. Granier,Patrick Gross,N.O. Jensen,Kim Pilegaard,Anders Lindroth,Achim Grelle,Christian Bernhofer,Thomas Grünwald,Marc Aubinet,Reinhart Ceulemans,Andrew S. Kowalski,Timo Vesala,Üllar Rannik,Paul Berbigier,Denis Loustau,Jón Guðmundsson,H. Thorgeirsson,A. Ibrom,K. Morgenstern,Robert Clement,John Moncrieff,Leonardo Montagnani,Stefano Minerbi,Paul G. Jarvis +29 more
TL;DR: Data of net ecosystem carbon exchange, collected between 1996 and 1998 from 15 European forests, confirm that many European forest ecosystems act as carbon sinks and indicate that, in general, ecosystem respiration determines netcosystem carbon exchange.
Journal ArticleDOI
Environmental controls over carbon dioxide and water vapor exchange of terrestrial vegetation
Beverly E. Law,Eva Falge,Lianhong Gu,Dennis D. Baldocchi,Peter S. Bakwin,Paul Berbigier,Kenneth J. Davis,A. J. Dolman,Matthias Falk,Jose D. Fuentes,Allen H. Goldstein,A. Granier,Achim Grelle,David Y. Hollinger,Ivan A. Janssens,Paul G. Jarvis,Niels Otto Jensen,Gabriel G. Katul,Y. Mahli,Giorgio Matteucci,Tilden P. Meyers,Russell K. Monson,William Munger,Walter C. Oechel,Richard J. Olson,Kim Pilegaard,H. Thorgeirsson,Riccardo Valentini,Shashi B. Verma,Timo Vesala,Kell B. Wilson,Steven C. Wofsy +31 more
TL;DR: The authors compared seasonal and annual estimates of CO2 and water vapor exchange across sites in forests, grasslands, crops, and tundra that are part of an international network called FLUXNET, and investigated the responses of vegetation to environmental variables.
Journal ArticleDOI
The human footprint in the carbon cycle of temperate and boreal forests
Federico Magnani,Maurizio Mencuccini,Marco Borghetti,Paul Berbigier,Frank Berninger,Sylvain Delzon,Achim Grelle,Pertti Hari,Paul G. Jarvis,Pasi Kolari,Andrew S. Kowalski,Harry Lankreijer,Beverly E. Law,Anders Lindroth,Denis Loustau,Giovanni Manca,John Moncrieff,Mark Rayment,Vanessa Tedeschi,Riccardo Valentini,John Grace +20 more
TL;DR: It is shown that the temporal dynamics following stand-replacing disturbances do indeed account for a very large fraction of the overall variability in forest carbon sequestration, and that mankind is ultimately controlling the carbon balance of temperate and boreal forests.
