A dataset of glacier surface motion distribution in High Mountain Asia during 2019–2020 with GF-3 imagery

And the spatial resolution of the final result is around 12 m by sampling interval of GF-3 with FSI imaging mode. An overall accuracy of about 0.5 m is given by the statistical analysis of the residual movement in the non-glacial region. The results demonstrate that the glacier velocity in the accumulation area is generally faster than that in the terminal or ablation part, some small and medium-sized glaciers have relatively strong activities.

Generally, the ice velocity reveals a positive correlation with topography and climate. The dataset could serve as the basis in research of glacial mass balance in Qinghai-Tibet Plateau, providing statistical support to understand the relationship between ice and climate change in High Mountain Asia. Finally, this study could promote the application of domestic remote sensing data in glacier activity and climate change on a deeper level.
