中国4km分辨率逐日日照时数数据集(2000-2020年)
收藏资源简介:
数据集为2000-2020年中国4 km逐日日照时数数据,利用699个气象站数据通过空间插值生成,以NetCDF文件格式存储。文件名“CDMet_ssd_yyyy.nc”,其中CDMet表示数据集名称,ssd表示日照时数,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 provides daily 4-kilometer resolution sunshine duration data across China for the period 2000–2020. It was generated via spatial interpolation using observations from 699 meteorological stations, and stored in NetCDF format. The filename follows the pattern "CDMet_ssd_yyyy.nc", where "CDMet" denotes the dataset name, "ssd" stands for sunshine duration, and "yyyy" represents the year ranging from 2000 to 2020. Each .nc file stores full-year data. Each NetCDF file has three dimensions: longitude, latitude, and time. The time dimension contains 365 layers (366 for leap years), corresponding to daily data of the year, with the first layer representing January 1st, the last layer representing December 31st, and the rest arranged in chronological order. To save storage space, the data is scaled to the int16 format.
