讲座简介：

Numerous efforts to measure land surface fluxes, from leaf to canopy scales, have significantly advanced the field of biogeoscience. However, scaling these estimates to larger spatial and temporal scales remains a challenge. Recent advancements in remote sensing offer new opportunities to bridge these scaling gaps. In this presentation, I propose that emerging satellite data can support the robust upscaling of land surface fluxes across space, using constellations of low Earth orbit satellites; time, through geostationary satellites; and spectrum, via optical, thermal, and microwave sensors. Finally, I recommend the development of a long-term network integrating tower-based hyperspectral, thermal, and microwave instruments to rigorously evaluate the upscaling of land surface fluxes.

Youngryel Ryu received his BS and MCP degrees from Seoul National University and a PhD in biometeorology from UC Berkeley in 2010. He then completed a research internship at Microsoft Research and a postdoctoral fellowship at Harvard University. He is currently a full professor at Seoul National University. Dr. Ryu was the recipient of the NASA Earth System Science Fellowship and has served as an editor for Remote Sensing of Environment (since 2018) and Global Change Biology (since 2023). His group's work has been recognized as Highly Cited Researcher (HCR) by Clarivate. His research group investigates biosphere-atmosphere interactions across multiple spatial and temporal scales by integrating near-surface and satellite remote sensing, leaf-to-ecosystem observations, and ecosystem models under the vision: "A sustainable world where ecological information is available and accessible to everyone."
