CNRDv1.0: the China natural runoff dataset version 1.0

The quality-controlled gridded naturalized runoff dataset, the China natural runoff dataset version 1.0 (CNRD v1.0), is reconstructed by using a comprehensive model parameter uncertainty analysis framework within a land-surface model. CNRD v1.0 provides daily, monthly and annual 0.25° runoff estimates for the period 1961–2018 over China. CNRD v1.0 was generated using the Variable Infiltration Capacity model with a comprehensive parameter uncertainty analysis framework incorporating parameter sensitivity analysis, optimization and regionalization based on 200 natural or near-natural gauge catchments. <br> Global attributes: Variables = Total runoff (qtot) Data Types = Histrorical reconstruction Date format = NetCDF4 Temporal Range = 1961-01-01 to 2018-12-31 Spatial extent = 18.6250° N ~53.6250° N, 73.375° E ~135.1250° E Units = mm Missing value = -9999 _FillValue = -9999 <br> Publications: 1.

本数据集为经过质量控制的网格化天然径流数据集——中国天然径流数据集版本1.0（China Natural Runoff Dataset Version 1.0，简称CNRD v1.0），在陆面模型框架内，采用综合模型参数不确定性分析框架完成重建。CNRD v1.0 提供了1961—2018年期间覆盖中国全域的日、月、年尺度0.25°经纬度分辨率径流估算数据。
CNRD v1.0 基于可变下渗能力模型（Variable Infiltration Capacity Model，简称VIC模型）构建，结合了涵盖参数敏感性分析、参数率定以及基于200个天然或近天然水文站控制流域的参数区域化的综合参数不确定性分析框架。
