A daily gap-free normalized difference vegetation index dataset from 1981 to 2023 in China

The daily gap-free NDVI product covers a spatial extent of 18.16°N to 53.56°N and 73.44°E to 135.09°E with a spatial resolution of 0.05°. The NDVI product from June 24, 1981 to May 10, 2023 is available at figshare repository. The NDVI data for each year is individually stored as a standard Network Common Data Form, version 4 (NetCDF-4, NC4) format and a total of 43 NC4 files are provided. The file names follow the structure of “Daily_Gap-filled_NDVI_YYYY.nc4”, where “YYYY” represents the year. Additional information, such as the scale factor, is stored in the files.

本每日无间隙归一化差分植被指数（NDVI）数据集的空间覆盖范围为北纬18.16°至53.56°、东经73.44°至135.09°，空间分辨率为0.05°。该数据集的时间跨度为1981年6月24日至2023年5月10日，可于figshare仓储获取。每年的NDVI数据均以标准网络通用数据格式第4版（Network Common Data Form version 4，NetCDF-4，简称NC4）单独存储，本次共提供43个NC4格式文件。文件命名遵循"Daily_Gap-filled_NDVI_YYYY.nc4"格式，其中"YYYY"代表年份。文件中还存储了比例因子等附加信息。
