One problem with the combined use of different pan-European layers in JRCs Carbon Budget Information System is related to aspects of scale, minimum mapping unit, and generalization. The aim of this paper is to report on a study addressing the differences in scale between the various input layers. The conclusion from the measurements is that the use of average values for the soil parameters in a simulation may introduce an error of up to 28% in the Net Ecosystem Production (NEP) compared to the sum of the outcome of separate simulations based on homogeneous soil regions. These errors include both over-and under estimation of the NEP. Future experiments should point out whether the error is compensated for when analyzing large areas.
