Dr. Daqing Yang is a Research Scientist in the Watershed Hydrology and Ecology Research Division, Environment and Climate Change Canada (ECCC). He is also Affiliate Research Professor at the International Arctic Research Center, Univ. of Alaska Fairbanks, and Adjunct Member of Graduate Program at Geography Dept, York University. Dr. Yang has extensive research experience (in China, Canada, USA, Japan, and Norway) in the areas of cold region/northern hydrology and climate. He led many NSF/NOAA/NASA/CliC/ECCC research projects of large-scale (watershed) hydrologic and climatic processes and their interactions with human impacts. He is an expert in applications/validations of remote sensing data/products, observational methods/techniques, particularly snowfall and precipitation observations and dataset development/analyses in the northern regions. He contributes to IPCC Ocean and Cryosphere Theme Report and Artic Council’s Snow, Water, Ice and Permafrost in the Arctic (SWIPA) assessment. He is the Associate Editor for Journal of Hydrology and EGU’s Atmospheric Measurement Technique, and a Guest Editor for a special issue of Polar Science. He has edited/co-edited 3 IAHS Red Books on topics of cold region hydrology and water balance analyses.
