Landsat spectral index products over Qinghai-Tibetan Plateau

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. 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. The dataset consists of 8 index products (NDVI, EVI, SAVI, MSAVI, NBR, NDMI, NDWI, SI ) with folders, and each spectral index product consists of 6 subsets with Folders in total. Folder XXX means the corresponding spectral product in year XXX, e.g. NDVI\1990 is the NDVI product in 1990. Each folder comprises about 170 ZIP files, and each zip file includes spectral index result, QA file, thumbnail and metadata file.
