From top to bottom. Regression of observed and modelled NEE, GPP and TER differences in 2003 vs. 2002 at the eddy-covariance sites as a function of observed air July to September temperature differences (left) and of April to October rainfall differences (right). On the same scale is shown the regression of simulated NEE, GPP and TER changes in 2003 vs. 2002 for all the model grid points over Europe, defined here as the area bounded by 10°W and 37°E in longitude and by 36°N and 69°N in latitude. The eddy covariance observations and the model simulations over Europe illustrate the fact that there is a larger correlation of flux changes with rainfall than with temperature changes. The largest correlation is found for GPP.
