The PISCO-ARNOVIC product

This product was developed using the daily gridded (0.1° x 0.1°) precipitation and evapotranspiration PISCO dataset and the coupled ARNO/VIC+RAPID model. The product has coverage throughout Peru, including transboundary basins with neighboring countries. The national model simulates mean daily flows across 11,913 river reaches to provide a fine-scale representation at the national scale. The model was calibrated and validated using observed daily flow records from 43 fluviometric stations during the period 1981 - 2020. Flow simulations will be yearly updated for users.
