AB  - The time-series data of the Normalized Difference Vegetation Index (NDVI) is a crucial indicator for global and regional vegetation monitoring.  However, the current assessment of global and regional long-term vegetation changes is subject to large uncertainties due to the lack of spatiotemporally continuous time-series data sets.Using the MOD13Q1 and GIMMS NDVI 3g vegetation index datasets, combined with digital elevation models and other data sources, a random forest downscaling model was employed to generate a 250 m spatial resolution NDVI data product for the Tibetan Plateau from 1982 to 2020, which was subsequently validated and evaluated.Compared to the MODIS NDVI product, the fused product shows RMSE and mean absolute error ranging from 0 to 0.075 and from 0 to 0.05, respectively, with R2 values mostly above 0.7. This data can provide essential support for research on the grassland ecosystem of the Tibetan Plateau.
