The box plots of (a) NSE, (b) RMSE, and (c) ATPE metrics for four models in four experiments. The abscissa represents experiments 1, 2, 3, and 4, which are aligned with the experiments discussed in subsections Experiment 1: individual rainfall-runoff modeling for each catchment to Experiment 4: Rel-Informer model applied to ungauged catchments, respectively.
