Journal ArticleDOI
Europe-wide reduction in primary productivity caused by the heat and drought in 2003
Philippe Ciais,Markus Reichstein,Nicolas Viovy,A. Granier,Jérôme Ogée,Vincent Allard,M. Aubinet,Nina Buchmann,C. Bernhofer,Arnaud Carrara,Frédéric Chevallier,N. de Noblet,Andrew D.

TL;DR: An increase in future drought events could turn temperate ecosystems into carbon sources, contributing to positive carbon-climate feedbacks already anticipated in the tropics and at high latitudes.
Journal ArticleDOI

Markus Reichstein,Eva Falge,Dennis D. Baldocchi,Dario Papale,Marc Aubinet,Paul Berbigier,Christian Bernhofer,Nina Buchmann,Nina Buchmann,Tagir G. Gilmanov,A.

Seufert,Francesco Primo Vaccari,Timo Vesala,Dan Yakir,Riccardo Valentini +33 more
TL;DR: In this paper, the authors analyse the effect of extrapolation of night-time values of ecosystem respiration into the daytime; this is usually done with a temperature response function that is derived from long-term data sets.
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
Gap filling strategies for defensible annual sums of net ecosystem exchange

TL;DR: In this paper, the impact of different gap filling methods on the annual sum of net ecosystem exchange (F NEE ) responses is investigated, based on mean diurnal variation, look-up tables (LookUp), and nonlinear regressions (Regr).
Journal ArticleDOI

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.
