中国4 km分辨率逐日平均风速数据集（2000-2020年）

数据集为2000-2020年中国逐日平均风速数据，空间分辨率4 km，利用699个气象站数据空间插值生成，以NetCDF文件格式存储。文件名“CDMet_win_yyyy.nc”，其中CDMet表示数据集名称，win表示10m平均风速，yyyy表示年份（2000-2020），每个nc文件存储一整年的数据。每个nc文件有3个维度，分别代表经度、纬度和时间。时间维度有365个图层（闰年为366），代表该年每天的数据，第一个图层代表1月1日，最后一个图层代表12月31日，以此类推。为了节省存储空间，数据被缩放为 int16 格式。

This dataset contains daily average wind speed data across China from 2000 to 2020, with a spatial resolution of 4 km. It was generated via spatial interpolation using data from 699 meteorological stations, and stored in NetCDF file format. The file naming convention is "CDMet_win_yyyy.nc", where CDMet represents the dataset name, win denotes 10-meter average wind speed, and yyyy corresponds to the year (2000–2020). Each .nc file stores full-year data. Each file includes three dimensions: longitude, latitude, and time. The time dimension has 365 layers (366 for leap years), representing the daily data of the corresponding year, with the first layer standing for January 1st and the last layer for December 31st in chronological order. To save storage space, the data is scaled to the int16 format.
