China natural runoff dataset version 1.0 (CNRD v1.0)

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.Global attributes:Variables = Total runoff (qtot)<br>Data Types = Histrorical reconstruction<br>Date format = NetCDF4Temporal Range = 1961-01-01 to 2018-12-31 <br>Spatial extent = 18.6250° N ~53.6250° N, 73.375° E ~135.1250° EUnits = mmMissing value = -9999<br>_FillValue = -9999Publications:1.

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v1.0（China Natural Runoff Dataset v1.0，简称CNRD v1.0），是依托陆面模型，通过综合模型参数不确定性分析框架重建得到的。CNRD v1.0提供了1961–2018年期间中国全域范围内每日、每月及年度尺度下0.25°分辨率的径流估算数据。该数据集基于可变下渗容量模型（Variable Infiltration Capacity model，VIC）构建，采用了包含参数敏感性分析、参数率定及基于200个天然/近天然水文观测流域的区域化处理在内的综合参数不确定性分析框架。
