Yifan Cheng: Climate impacts on Alaska and Yukon hydrometeorology: an ongoing modeling effort guided by Indigenous Knowledge

Yifan Cheng (NCAR)

INSTAAR Seminar Series. Hybrid event, in person and via Zoom

Location: Sievers Conference Room (SEEC S228). 4001 Discovery Drive, Boulder, CO

Audience: All are welcome

Abstract: Drastic hydrological changes in the arctic greatly impact local Alaskan communities, who largely rely on inland freshwater systems for subsistence fishing and transportation. As part of the US NSF Navigating the New Arctic program, this study actively engages indigenous participation, e.g., a project specific Indigenous Advisory Council, to help inform our research design, analysis, and deliverables. With Indigenous participation, we aim to provide representationally appropriate climate and hydrological information that is not only useful but usable to support decision-making concerning the mitigation and adaptation of climate crises. Here we will present how we conduct knowledge co-production and use Indigenous Knowledge to inform regional climate modeling. We specifically focused on coupled land and atmospheric modeling and developed an optimization framework to improve the hydrologic simulations in the Alaska and Yukon River Basin.

After presentation: There will be time for informal discussion with the speaker after the presentation; cookies and coffee will be served.
