Solar-Induced Chlorophyll Fluorescence (SIF): Towards a Better Understanding of Vegetation Dynamics and Carbon Uptake in Arctic-Boreal Ecosystems
May 1, 3:30 to 4:30 pm

Soils 415 and Zoom 

Abstract: Solar-Induced chlorophyll Fluorescence (SIF), a good proxy for vegetation CO2 uptake, has been broadly utilized to assess vegetation dynamics and carbon uptake at the global scale. However, the full potential and limitations of SIF in the Arctic-Boreal region have not been explored. Therefore, this presentation summarizes the latest insights into Arctic-Boreal carbon uptake through SIF analyses, underscoring the advances and challenges of SIF in solving emergent unknowns in this region. We will present evidence that cross-scale SIF measurements complement each other, offering valuable perspectives on Arctic-Boreal ecosystems. 


Event Speaker

Bio: Dr. Rui Cheng is an Assistant Professor in the Department of Bioproducts and Biosystems Engineering at the University of Minnesota, Twin Cities. Her research focuses on evaluating global vegetation-climate feedbacks, such as carbon, water, and energy fluxes between land and atmosphere, using a fusion of remote sensing techniques, specifically in regions with limited direct measurements, including the Arctic, tropics, and mountainous regions. Dr. Cheng is the guest editor for Environmental Research - Ecology. She serves on remote sensing and foliar sampling technical working groups with NSF’s National Ecological Observatory Network (NEON), Ameriflux Year of Remote Sensing Committee, and Community of Practice for Fair & Equitable Climate Solutions (CarbonDew). Dr. Cheng received her Ph.D. from the California Institute of Technology, M.S. from Lehigh University, and B.S. from Sun Yat-sen University. Please reach out to Dr. Cheng for collaborations and opportunities.
