  "description": "This product provides a national-scale dataset of simulated daily streamflow across Peru, developed using the PISCO gridded precipitation and evapotranspiration dataset at 0.1\u00b0 \u00d7 0.1\u00b0 spatial resolution, coupled with the ARNO/VIC rainfall\u2013runoff model and the RAPID river routing scheme. The dataset covers the entire Peruvian territory, including transboundary river basins shared with neighboring countries.\r\n\r\nThe modeling framework generates mean daily discharge for 11,913 river reaches, enabling a fine-scale representation of hydrological conditions at the national level. Model calibration and validation were performed using observed daily streamflow records from 43 gauging stations over the period 1981\u20132020, ensuring consistency with observed hydrological dynamics.\r\n\r\nThis dataset is designed to support hydrological analysis, monitoring, and decision-making, and will be regularly updated to incorporate new simulations and improvements.",
