Landsat surface reflectance products based on BRDF correction over Qinghai-Tibetan Plateau

The surface reflectance products based on BRDF correction can decrease the variability of surface reflectance caused by changes in solar incidence angles and satellite viewing angles, so these products perform higher accuracy and radiative consistency by comparing with surface reflectance products that only undergo atmospheric correction. By using 6S-based atmospheric correction method and the C-factor BRDF correction method, the high-quality surface reflectance products over the Qinghai-Tibetan Plateau in 1990, 2000, 2010, 2015, 2020, and 2022 are generated. The processing steps to these products include radiometric calibration, atmospheric correction, and BRDF correction. The results are finally saved in GeoTIFF format, accompanied by corresponding quality and metadata files. The product can be applied in fields such as quantitative retrieval of remote sensing surface parameters, agriculture and forestry, and climate change research in Qinghai-Tibetan Plateau. The dataset consists of 6 subsets with folders in total. Folder XXX means the surface reflectance product in year XXX, e.g. Folder 1990 is the surface reflectance product in 1990. Each folder comprises about 170 folders, and each folder includes surface reflectance results of each band, QA file, thumbnail and metadata file.
