1979-2018年中国区域0.1度地面风速驱动数据集

数据集是以国际上现有的Princeton再分析资料、GLDAS资料、GEWEX-SRB辐射资料，以及TRMM降水资料为背景场，融合了中国气象局常规气象观测数据制作而成。数据为NETCDF格式，时间分辨率为3小时，水平空间分辨率为0.1°。原始资料来自于气象局观测数据、再分析资料和卫星遥感数据。已去除非物理范围的值，采用ANU-Spline统计插值。精度介于气象局观测数据和卫星遥感数据之间，好于国际上已有再分析数据的精度。

This dataset is developed by fusing routine meteorological observation data from the China Meteorological Administration (CMA), using internationally available Princeton reanalysis data, GLDAS data, GEWEX-SRB radiation data, and TRMM precipitation data as background fields. The dataset is stored in NETCDF format, with a temporal resolution of 3 hours and a horizontal spatial resolution of 0.1°. Original data sources include meteorological observation data, reanalysis data and satellite remote sensing data. Non-physically unrealistic values have been removed, and the ANU-Spline statistical interpolation method is applied. Its accuracy falls between that of CMA routine observation data and satellite remote sensing data, and outperforms existing international reanalysis datasets.
