Comparison of modelled and observed carbon flux anomalies. Global modelling results (NPP, Rh, NEE) and atmospheric reference data representing changes in ecosystem physiology. Negative values of NEE, NPP and Rh denote carbon uptake by the land biosphere. Negative values of measured atmospheric ΔCO2 denote a reduction it's rate of increase.
