[A-CG54] Biogeochemical Cycles in Land Ecosystem

Tue. May 26, 2026 5:15 PM - 7:00 PM Poster Hall (Exhibition Hall 7&8, Makuhari Messe)

Terrestrial ecosystem influences global climate through cycles of water, carbon, and nitrogen between the land surface and the 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, H2O, and other trace gas flux measurements, has promoted multidisciplinary studies not only for the flux measurement community but also for remote sensing and biosphere modeling communities. This session unites those multidisciplinary 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 from last year.
