**About the Editors**

**Yongqiang Zhang** has 24 years of experience in hydrological modelling and remote sensing hydrology. He is currently a Distinguished Professor in Hydrology and Water Resources in the Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences. He worked in CSIRO as the Research Scientist, Senior Research Scientist and Principal Research Scientist in 2006–2018. He is the prestigious Alexander von Humboldt Fellow. He has won 12 professional awards, including 2012 GN Alexander Medal. Professor Zhang is a global leader in hydrology and water resource studies that incorporate remote sensing techniques into hydrological modelling. Dr Zhang has 152 ISI publications, including journal papers published in Nature stables (*Nature Climate Change* (IF = 24.624), *Nature Communications* (IF = 14.526)) and top field research journals; *Water Resources Research* (IF = 5.240), *Journal of Hydrology* (IF = 5.722), *Journal of Geophysical Research: Atmospheres* (IF = 4.261), *Remote Sensing of Environment* (IF = 10.164), and *Global Change Biology* (IF = 10.863). He has more than 80 journal papers published in top journals, of which 54 journal papers have been published since 2016. He has Google Scholar citations of >10,000, ISI Web of Science citations of >6140 and a H-index of 41. His major research contributions include developing novel hydrological modelling approaches by using remote sensing techniques to significantly improve runoff (and streamflow and water availability) simulations and predictions in gauged and ungauged catchments, and the development of the PML evapotranspiration model, a representative diagnostic model to evaluate IPCC global climate model simulations. Professor Zhang is serving for six peer-reviewed journals: including as Associate Editor of the *Journal of Hydrology*, the *Journal of Geophysical Research: Atmospheres* and *Science of Remote Sensing*, and as an Editorial Board Member of *Remote Sensing of Environment*.

**Dongryeol Ryu** is an Associate Professor in the Department of Infrastructure Engineering, The University of Melbourne, Australia. Previously, he worked as a Research Physical Scientist in the Hydrology and Remote Sensing Lab., US Department of Agriculture (USDA), Agricultural Research Services (ARS). He is a NASA Earth Science Graduate Fellow and a recipient of the University of California, Irvine Medal fellowship. He currently leads the Environmental Sensing and Modelling Lab. Specialized in remote sensing of land surface variables such as soil moisture and vegetation characteristics, their spatial and temporal variability, and hydrological applications. He also investigates the roles of land surface changes in hydroclimate processes. Dongryeol received his Ph.D. degree in Earth System Science from the University of California, Irvine in 2006, and the B.S. and M.S. degrees in Geological Sciences from Seoul National University, Korea.

**Donghai Zheng** has 10 years of experience in land surface modelling and microwave remote sensing of soil moisture and freeze–thaw dynamics. He is currently a Professor in the Institute of Tibetan Plateau Research, Chinese Academy of Sciences. He worked in ITC of University of Twente as the Researcher in 2015–2018. Professor Zheng is a recognized international expert in the use of microwave remote sensing and land surface model to quantify soil freeze–thaw process and water cycle over the Tibetan Plateau (TP). He has 40+ ISI papers published in research field top journals (e.g., *Remote Sensing of Environment* (IF = 10.164), *IEEE Transactions on Geoscience and Remote Sensing* (IF = 5.6), *Journal of Geophysical Research: Atmospheres* (IF = 4.261)). The main achievements of his work are (i) highlighting the importance of coupled heat and water exchange and soil freeze–thaw processes for quantifying water cycle over the TP, (ii) revealing microwave emission characteristics of frozen layered soil via conducting an ground-based L-band radiometry (ELBARA-III) field campaign on the TP since 2016 and developing an integrated land surface and microwave radiative transfer model, and (iii) quantifying the sampling depth of L-band radiometry and retrieving liquid water content for both frozen and thawed soil conditions. The ELBARA-III field site is selected as calibration/validation site for ESA's SMOS and NASA's SMAP satellite missions.
