2011-2021年中国0.05°向下短波辐射产品数据集

2011-2021年中国0.05°向下短波辐射产品数据集提供了月尺度的向下短波辐射数据，基于2011-2021年小时分辨率的ERA陆地产品数据生产。ERA5是ECMWF（欧洲中期天气预报中心）对1950年1月至今全球气候的第五代大气再分析数据集，提供了2m空气温度、2m露点温度、总降水量、平均海平面气压、表面气压、10m的u风分量和10m的v风分量。利用空间统计插值方法（Spline）将该0.1度空间分辨率数据进一步降尺度到0.05°空间分辨率，最后将小时分辨率数据累计为逐月数据。

The 0.05° downward shortwave radiation product dataset over China spanning 2011–2021 provides monthly-scale downward shortwave radiation data, which is generated using hourly-resolution ERA5 Land product data from 2011 to 2021. ERA5 is the fifth-generation global atmospheric reanalysis dataset for global climate from January 1950 to the present, developed by ECMWF (European Centre for Medium-Range Weather Forecasts). This dataset supplies 2-meter air temperature, 2-meter dew point temperature, total precipitation, mean sea level pressure, surface pressure, 10-meter u-component of wind, and 10-meter v-component of wind. Subsequently, spatial statistical interpolation (Spline) was utilized to further downscale the 0.1° spatial resolution ERA5 Land data to 0.05° spatial resolution, and finally the hourly-resolution data was accumulated into monthly-scale datasets.
