中国及周边地区长时序Landsat系列卫星地表反射率（LSR）产品集

中国及周边地区长时序Landsat系列卫星地表反射率（LSR）产品集是基于中国卫星遥感地面站存档的Landsat系列数据进行大气校正后得到的，空间分辨率为30m，时间范围为1980s-2021年，包含地表反射率波段（Landsat5/7地表反射率波段为B1, B2, B3, B4, B5, B7；Landsat5/7地表反射率波段为B1, B2, B3, B4, B5, B6, B7）、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-term Landsat Surface Reflectance (LSR) product set for China and its surrounding areas is derived from atmospheric correction of archived Landsat data from the China Satellite Remote Sensing Ground Station. It has a spatial resolution of 30 meters and covers the time range from the 1980s to 2021. The product set includes surface reflectance bands (Landsat5/7 surface reflectance bands are B1, B2, B3, B4, B5, B7; Landsat8 surface reflectance bands are B1, B2, B3, B4, B5, B6, B7), quality assessment (QA) files, metadata XML files, and thumbnail images, etc. To save storage space, the results are multiplied by 10000, stored in 16-bit format, and compressed using LZW lossless compression.
