Climate impacts on terrestrial hydrology and hydrometeorology in Alaska and Yukon River Basin: a modeling effort guided by Indigenous Knowledge

The freshwater cycle in the Arctic is greatly affected by anthropogenic climate change. To provide “useable” rather than just “useful” climate information, we actively engage Indigenous participation in the research progress. As a foundation of capturing a trustworthy climate sensitivity of the freshwater cycle, we performed a multi-objective optimization on snow and river flow for a state-of-the-science land model, the Community Terrestrial Systems Model. Then we run the coupled land-atmosphere modeling using a Pseudo Global Warming (PGW) method and the optimized land parameters to model one historical and two future climate scenarios.
