1979-2018年中国区域0.1度地面气压驱动数据集

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 constructed by fusing routine meteorological observation data from the China Meteorological Administration (CMA) with background fields sourced from internationally available Princeton reanalysis data, GLDAS data, GEWEX-SRB radiation data, and TRMM precipitation data. The data is stored in NETCDF format, with a 3-hour temporal resolution and 0.1° horizontal spatial resolution. The original data sources cover meteorological observation data, reanalysis data and satellite remote sensing data. Non-physical values have been removed from the dataset, and statistical interpolation using the ANU-Spline method has been applied. The accuracy of this dataset falls between that of CMA routine meteorological observation data and satellite remote sensing data, and is superior to that of existing international reanalysis datasets.
