The data of this topic comes from the National Key Program for Basic Research and Development (973 Program) project "Research on Cryospheric Changes and Their Impacts". This project was officially launched in April 2013, with Qin Dahe, academician of the Chinese Academy of Sciences (CAS), as the leader of the expert group, and Ding Yongjian, researcher of the Northwest Institute of Eco-Environment and Resources, Chinese Academy of Sciences, as the chief scientist. The project is jointly undertaken by thirteen organizations, including the Northwest Institute of Eco-Environment and Resources, Chinese Academy of Sciences, the Qinghai-Tibet Plateau Research Institute, the Chengdu Institute of Mountain Hazards and Environment of the Ministry of Water Resources, Tsinghua University, Lanzhou University and others. The project aims to carry out research on cryosphere change, impacts and adaptations on three major scientific issues of the cryosphere, namely, the mechanism of cryosphere change, the interaction between the cryosphere and climate, and the impacts and adaptations to cryosphere change, which is of great significance to promote the international cryosphere science towards the systematization of disciplines, and to improve the overall level of cryosphere science. A total of 48 datasets have been generated by the project, including data products such as field observations of glaciers, permafrost and snow cover in the cryosphere, remote sensing inversion and numerical simulation.
