Markus Reichstein,Eva Falge,Dennis D. Baldocchi,Dario Papale,Marc Aubinet,Paul Berbigier,Christian Bernhofer,Nina Buchmann,Nina Buchmann,Tagir G. Gilmanov,A. Granier,Thomas Grünwald,Katka Havránková,Hannu Ilvesniemi,Dalibor Janouš,Alexander Knohl,Alexander Knohl,Tuomas Laurila,Annalea Lohila,Denis Loustau,Giorgio Matteucci,Tilden P.

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.
Journal ArticleDOI
Evidence for Soil Water Control on Carbon and Water Dynamics in European Forests during the Extremely Dry Year: 2003
André Granier,Markus Reichstein,Nathalie Bréda,Ivan A. Janssens,Eva Falge,Philippe Ciais,Thomas Grünwald,M. Aubinet,Paul Berbigier,Christian Bernhofer,Nina Buchmann,Osvaldo Facini,Giacomo Grassi,B. Heinesch,Hannu Ilvesniemi,Petri Keronen,Alexander Knohl,Barbara Köstner,Fredrik Lagergren,Anders Lindroth,Bernard Longdoz,Denis Loustau,J. Mateus,Leonardo Montagnani,C. Nys,Eddy Moors,Dario Papale,Marianne Peiffer,Kim Pilegaard,Gabriel Pita,Jukka Pumpanen,Serge Rambal,Corinna Rebmann,Abel Rodrigues,Guenther Seufert,John Tenhunen,Timo Vesala,Qiuwang Wang +37 more
TL;DR: In this paper, the authors used continuous carbon and water flux measurements at 12 European monitoring sites covering various forest ecosystem types and a large climatic range in order to characterise the consequences of this drought on ecosystems functioning.
Journal ArticleDOI
Reduction Of Ecosystem Productivity And Respiration During The European Summer 2003 Climate Anomaly: A Joint Flux Tower, Remote Sensing And Modelling Analysis
Markus Reichstein,Markus Reichstein,Philippe Ciais,Dario Papale,Riccardo Valentini,Steven W. Running,Nicolas Viovy,Wolfgang Cramer,André Granier,Jérôme Ogée,Vincent Allard,M. Aubinet,Ch.

TL;DR: In this paper, the effect of the 2003 heatwave on the European biosphere's productivity and carbon balance was analyzed using the EOS-MODIS sensor data and ecosystem modelling, showing that the drop in productivity was not primarily caused by high temperatures but rather by limitation of water.
Journal ArticleDOI
Comparison of different chamber techniques for measuring soil CO2 efflux
Jukka Pumpanen,Pasi Kolari,Hannu Ilvesniemi,Kari Minkkinen,Timo Vesala,Sini Niinistö,Annalea Lohila,Tuula Larmola,Micaela Morero,Mari Pihlatie,Ivan A. Janssens,Jorge Curiel Yuste,José M. Grünzweig,Sascha Reth,Jens-Arne Subke,Kathleen Savage,Werner L. Kutsch,Geir Østreng,Waldemar Ziegler,P. M. Anthoni,Anders Lindroth,Pertti Hari +21 more
TL;DR: In this article, the effect of soil moisture on chamber measurements was tested by wetting the fine quartz sand to about 25% volumetric water content, and the results showed that the chamber headspace concentration also affects the flux by altering the concentration gradient between the soil and the chamber.
Journal ArticleDOI
An underestimated role of precipitation frequency in regulating summer soil moisture
Chaoyang Wu,Jing M. Chen,Jukka Pumpanen,Alessandro Cescatti,Barbara Marcolla,Peter D. Blanken,Jonas Ardö,Yanhong Tang,Vincenzo Magliulo,Teodoro Georgiadis,Henrik Soegaard,David R. Cook,Richard Harding +12 more
TL;DR: In this article, the temporal and spatial relationship between summer soil water content (SWC) and the precipitation frequencies at various temporal scales, i.e., from half-hourly, 3, 6, 12 and 24 h measurements, were analyzed.
