The PISCO_HyD_ARNOVIC (v1.0) 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 the Peruvian territory including transboundary basins with neighboring countries. The ARNO/VIC+RAPID model simulates mean daily flows in 11,913 river reaches to obtain a fine representation at the national scale. The model was calibrated and validated using observed daily flow records from 43 stations fluviometric stations during the period 1981 - 2020. Flow simulations will be yearly updated for users.

本产品基于每日网格化（0.1° x 0.1°）降水量和蒸散量PISCO数据集，并结合ARNO/VIC+RAPID耦合模型开发而成。该产品覆盖整个秘鲁领土，包括与邻国接壤的跨境流域。ARNO/VIC+RAPID模型对11,913条河段日均流量进行模拟，以在国家尺度上实现精细化的流量表征。模型利用1981年至2020年间43个水文站观测到的日均流量记录进行校准和验证。流量模拟将每年更新，以供用户使用。
