[A-CG37] Biogeochemical Cycles in Land Ecosystem

Tue. May 28, 2024 1:45 PM - 3:15 PM 201A (International Conference Hall, Makuhari Messe)

convener:Munemasa Teramoto(Arid Land Research Center, Tottori University), Tomomichi Kato(Research Faculty of Agriculture, Hokkaido University), Kazuhito Ichii(Chiba University), Takeshi Ise(FSERC, Kyoto University), Chairperson:Munemasa Teramoto(Arid Land Research Center, Tottori University)

Terrestrial ecosystem influences global climate through cycles of water, carbon, and nitrogen between land surface and atmosphere. For a better understanding of those behaviors, a great effort has been made to develop a variety of approaches and techniques such as biometric surveys, eddy and chamber methods, near and satellite remote sensing, biosphere modeling, and so on. In particular, JapanFlux, founded in 2006 as a research network of CO2, CH4, H2O, and other trace gas flux measurements, has promoted multi-disciplinal studies not only for the flux measurement community but also for remote sensing and biosphere modeling communities. This session unites those multi-disciplinal activities and promotes oral and poster presentations on the role of the terrestrial ecosystem in material circulations of water, carbon, nitrogen, energy, and other substances by any approaches and techniques. This session takes over the former session in the last year.
