中国及周边地区长时序Landsat系列卫星归一化差值水分指数（NDMI）产品集

中国及周边地区长时序Landsat系列卫星归一化差值水分指数（NDMI）产品集是基于Landsat系列卫星地表反射率产品计算得到的，空间分辨率为30m，时间范围为1980s-2021年，包含NDMI、QA、元数据xml以及缩略图等文件内容，为了节省存储空间，将结果乘以了10000，存储成16位，并进行了LZW无损压缩。

The long-time-series Landsat Normalized Difference Moisture Index (NDMI) product set for China and its adjacent regions is derived from the Landsat series satellite surface reflectance products. It has a spatial resolution of 30 m, covers the time period from the 1980s to 2021, and includes files such as NDMI, QA, metadata XML, and thumbnails. To save storage space, the original NDMI values were multiplied by 10000, stored as 16-bit data, and compressed using LZW lossless compression.
