Abstract
Under the background of global warming, the Tibet Plateau shows a trend of warming and wetting. Remote sensing data can be used to effectively monitor the spatial and temporal changes of the surface water on the Tibet Plateau. Due to the dynamic characteristics of the water, and in order to study the long-term impact of climate and other factors on the water of the Qinghai-Tibet Plateau, we used the AVHRR daily reflectance time series from 1982 to 2020 to produce the 39-year daily water body mapping product (including water freezing information) on the Qinghai-Tibet Plateau. The overall accuracy of our product is up to 88.18% based on validation samples selected from 30m Landsat images. This product can provide fundamental data support for long-term water monitoring on the Qinghai Tibet Plateau.
