Summary
Abstract. Hydrological models are essential tools for assessing changes in the hydrological cycle, enabling detailed quantification of runoff (Q), total water storage (TWS), and actual evapotranspiration (AET). Precipitation (P) and potential evapotranspiration (PET) are the two major drivers in modeling these components, with the influence of P more extensively studied than PET. This study evaluates the impact of PET method selection on AET, Q, and TWS using 12 PET formulations categorized as temperature-based, radiation-based, and combinational. We applied the mesoscale Hydrological Model (mHM) to simulate 40 years of hydrological components across 553 European catchments. PET effects were analyzed through trend analysis and the data concurrence index (DCI) across three catchment categor
