**About the Editors**

#### **Xuejia Wang**

Xuejia Wang is a climate scientist and Professor of Climate and Cryosphere Studies at the College of Earth and Environment Sciences, Lanzhou University, China. His research, which uses meteorological observations, multi-source re-analyses, remote sensing datasets, and climate models, focuses on climate change and its impacts on the cryosphere, as well as various land–surface interactions (e.g., vegetation, soil freezing–thawing processes, and land–surface albedo) and the atmosphere. Dr. Wang has a Ph.D in Atmospheric Physics and Atmospheric Environment from the University of the Chinese Academy of Sciences. Prior to joining Lanzhou University, he was an Associated Researcher at the Northwest Institute of Eco-Environment and Resources, Chinese Academy of Sciences, China. He has published more than 50 peer-reviewed research papers and book chapters, with over 920 total citations. Dr. Wang serves as a committee member of the Youth Working Group in China Cryosphere Science and is a member of several research societies, such as the Geographical Society of China, the Research Society of the Tibetan Plateau, and the Society of China Cryosphere Science.

#### **Tinghai Ou**

Tinghai Ou is a climate scientist and Principal Research Engineer (specializing in climate modeling) in the Department of Earth Sciences at the University of Gothenburg, Sweden. His research interests, primarily based on climate modeling, are in regional climate change, land–atmosphere interaction, climate dynamics, and downscaling. Dr. Ou has a Ph.D. in Natural Science, specializing in Physical Geography, from the University of Gothenburg. Before holding his current position at the University of Gothenburg, he was a Post-Doctoral Fellow in the Faculty of Earth Systems & Environmental Sciences at the Chonnam National University, South Korea. He was also a visiting researcher at Pennsylvania State University, USA.

#### **Wenxin Zhang**

Wenxin Zhang is a Researcher at the Department of Physical Geography and Ecosystem Science, Lund University, Sweden. His research interests, which use satellite observation, ground-based measurements and Earth system models, include vegetation–climate feedback, Earth system modeling, underground greenhouse gas transmission, ecological modeling, and plant root modeling. He received his Ph.D in 2015 from Lund University. After that, until July 2018, he undertook postdoc research at the University of Copenhagen. He has published more than 40 peer-reviewed papers, with more than 1500 total citations. He also serves as a reviewer for several journals, such as the first draft of *IPCC AR6 Group 2 Report, Earth Science System Data*, and *Agricultural and Forest Meteorology*, etc.

#### **Youhua Ran**

Youhua Ran is currently a professor at the Northwest Institute of Eco-Environment and Resources, Chinese Academy of Sciences. He received his Ph.D in 2017 and his Master's degree in 2009 in Cartography and Geographical Information System from the University of the Chinese Academy of Sciences. His research interests include the remote sensing of the cryosphere, validation of remote sensing products, and sustainable watershed development. He has published more than 80 peer-review papers, with a total of more than 3300 citations. Dr. Youhua is a scientific committee member, Digital Polar Committee of the International Society for Digital Earth (ISDE), Digital Mountain Committee of the ISDE.
