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），依托陆面过程模型（land-surface model）内的综合模型参数不确定性分析框架重建得到。
CNRD v1.0可提供1961–2018年中国全域范围内日、月、年三个时间尺度下0.25°分辨率的径流估算数据。该数据集采用可变下渗容量模型（Variable Infiltration Capacity model，简称VIC模型），结合涵盖参数敏感性分析、参数率定及基于200个天然/近天然水文测站控制流域的参数区域化处理在内的综合参数不确定性分析框架生成。

全局属性如下：变量 = 总径流（Total runoff，qtot）；数据类型 = 历史重建数据；数据格式 = NetCDF4；时间范围 = 1961-01-01 至 2018-12-31；空间范围 = 北纬18.6250° ~ 53.6250°、东经73.375° ~ 135.1250°；单位 = 毫米；缺失值 = -9999；_FillValue = -9999。
