中国西北地区WRF模式气温和降水数据集（1979-2013）

本数据是WRF模式在中国西北地区对6h间隔的NCEP/DOE再分析数据单层嵌套降尺度到水平分辨率为 12km，东西方向格点数为364，南北方向格点数为251，垂直方向划分31层。模拟时间从1979-01-01,06:00:00开始，终止于2013-12-31,23:00:00。模式参数化方案如下：Kain Frisch积云对流方案，WSM3云微物理方案，RRTM长波方案，Dudhia短波方案，Noah陆面模式，YSU行星边界层方案。
数据集中的文件命名规则为：wrf_t2_YYYY.nc和wrf_rain_YYYY.nc，其中YYYY为年简写，t2为2m气温（单位℃），rain为地表总降水（单位mm）。

This dataset applies the WRF model to perform one-way nesting downscaling over Northwest China, forced by 6-hourly NCEP/DOE reanalysis data. The downscaled simulation domain has a horizontal resolution of 12 km, with 364 grid points in the east-west direction, 251 grid points in the north-south direction, and 31 vertical levels. The simulation period begins at 06:00:00 on January 1, 1979, and ends at 23:00:00 on December 31, 2013. The adopted model parameterization schemes are listed below: Kain-Frisch cumulus convection scheme, WSM3 cloud microphysics scheme, RRTM longwave radiation scheme, Dudhia shortwave radiation scheme, Noah land surface model, and YSU planetary boundary layer scheme.

The file naming convention for this dataset is: wrf_t2_YYYY.nc and wrf_rain_YYYY.nc, where YYYY denotes the four-digit year, t2 refers to 2-meter air temperature (unit: °C), and rain represents total surface precipitation (unit: mm).
