AB: A decade ago, a global network of sites measuring carbon dioxide, water vapor and energy fluxes between vegetation and the atmosphere was initiated. At present over 400 sites exist and together, with over 600 site years of data, they are producing a new view on the breathing of the terrestrial biosphere. In this presentation we will give an overview of the network and a survey of key findings. Among the topics discussed will be the range of annual carbon fluxes measured across a spectrum of climate space and plant functional types, quantification of interannual variability of fluxes, links between gross primary productivity and ecosystem respiration, detection of flux phenology and a presentation of new emergent processes like the role of diffuse light on canopy photosynthesis, the acclimation of canopy photosynthesis with temperature and the detection of pulses and lags in the temporal flux record.
