Zhang, Jing (author), Jia, Li (author), Menenti, M. (author), Zhou, Jie (author), Ren, Shaoting (author)Glacier and snow are sensitive indicators of regional climate variability. In the early 21st century, glaciers in the West Kunlun and Pamir regions showed stable or even slightly positive mass budgets, and this is anomalous in a worldwide context of glacier recession. We studied the evolution of snow cover to understand whether it could...journal article 2021
