Figure 5: (a) absolute and (b) relative number of outliers for simulated Ea /ETa attend (10988 days) for the 13 pedotransfer functions over all 12 USDA soil classes (11 for Clapp&Hornberger) and the homogeneous bare soil scenario. As some simulation runs did not converge, the total number of outliers was normalized to the number of converged simulations for each scenario and PTF combination.
