Abstract: Seven widely used remote sensing spectral index products (NDVI, EVI, SAVI, MSAVI, NDMI, NBR, and NDWI) and a unique salinity index (SI) for the Qinghai-Tibetan Plateau were generated based on The Landsat BRDF-correction-based surface reflectance products in the Qinghai-Tibet Plateau region. These products perform better radiometric consistency compared to the spectral index products computed based on surface reflectance products only undergoing atmospheric correction. The dataset comprises six periods of remote sensing index products for the years 1990, 2000, 2010, 2015, 2020, and 2022. The results are saved in GeoTIFF format and are accompanied by corresponding quality and metadata files. This product has significant application value in various research areas such as quantitative retrieval of remote sensing surface parameters, vegetation monitoring, ecosystem classification, water resource management, fire monitoring, and climate change research in Qinghai-Tibetan Plateau.
