Regardless of the important interest in worldwide hydrological modeling, handful of systematic evaluations of global hydrological models (gHMs) at the catchment scale happen to be carried out. This study investigates the functionality of four gHMs driven by 4 international observation-based meteorological inputs at simulating weekly discharges over 198 large-sized North American catchments for the 1971010 period. The 16 discharge simulations serve because the basis for evaluating gHM accuracy at the catchment scale inside the second phase with the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP2a). The (Z)-Semaxanib custom synthesis simulated discharges by the four gHMs are compared against observed and simulated weekly discharge values by two regional hydrological models (rHMs) driven by a global meteorological dataset for precisely the same period. We talk about the implications of each modeling approaches too because the influence of catchment Pinacidil MedChemExpress traits and global meteorological forcing when it comes to model functionality via statistical criteria and visual hydrograph comparison for catchment-scale hydrological studies. General, the gHM discharge statistics exhibit poor agreement with observations in the catchment scale and manifest considerable bias and errors in seasonal flow simulations. We confirm that the gHM method, as experimentally implemented via the ISIMIP2a, have to be utilised with caution for regional studies. We come across the rHM strategy to be extra trustworthy and advocate employing it for hydrological research, in particular if findings are intended to assistance operational decision-making.
