Model-based runoff in Northwestern Patagonia (41-46°S)

Dataset: The present dataset includes model-based runoff data for each of the 896 catchments with a surface area > 5 km2 draining into the coastal zone of Northwestern Patagonia (41-46°S). The data were generated using the Variable Infiltration Capacity (VIC) model. VIC is a semi-distributed, physically based hydrological model that simulates snow accumulation and melt, evapotranspiration, canopy interception, surface runoff, baseflow and other hydrological processes at sub-daily time steps. The model was forced with gridded meteorological data from PMET-sim and ERA5-Land for the period 1980-2020. The VIC model was calibrated (1985-2004) and validated (2005-2020) in 43 catchments using a split-sample approach. The calibration was performed using the Shuffled Complex Evolution algorithm included in the SPOTPY framework. The modelling approach achieved adequate performance of hydrological fluxes with modified Kling-Gupta efficiencies of 0.75 ± 0.12 and 0.64 ± 0.23 in the calibration and validation phases (daily timestep), respectively.
