| Water-use efficiency (WUE) has been recognized as an important characteristic of vegetation productivity in various natural scientific disciplines for decades, but only recently at the ecosystem level, where different ways exist to characterize water-use efficiency. 5 Hence, the objective of this research was (a) to systematically compare different ways of calculating ecosystem water-use efficiency (WUEe) from eddy-covariance measurements, (b) quantify the diurnal, seasonal and interannual variability of WUEe in relation to meteorological conditions, and (c) analyse between-site variability of WUEe as affected by vegetation type and climatic conditions, across sites in European forest 10 ecosystems. Day-to-day variability of gross primary productivity... |

| The Carbo Europe Regional Experiment Strategy (CERES), conducted between May and June 2005, aims to determine a spatiallyresolved regional balance of carbon dioxide fluxes using different methodological approaches bundled within an internationalframework. In this study we elucidated several meteorological and physiological parameters determining plant mediated exchangeprocesses using airborne hyperspectral reflectance measurements in synopsis with meteorological information like eddy fluxcovariance data. We used an airborne hyperspectral system to record spatial and temporal transects of vegetated areas surroundingflux tower sites in the Bordeaux / Landes Region (France). Alongside hyperspectral measurements a comprehensive range ofmeteorological and... |
