Session 8B Boundary Layer Processes and Biogeochemistry in Amazonia

Wednesday, 15 January 2020: 8:30 AM-10:00 AM
207 (Boston Convention and Exhibition Center)
Host: 22nd Conference on Atmospheric Chemistry

After more than three decades of field and theoretical studies in Amazonia, we have gained a great deal of knowledge about atmospheric boundary layer processes and biogeochemistry in one of the world’s rainiest and most ecologically diverse regions. This knowledge has been employed to improve regional and global weather and climate models. In addition, the international partnerships and collaborations forged to complete the research projects have contributed to the long-term legacy of capacity building and professional development of several cohorts of junior scholars.

Therefore, this proposal seeks to organize special conference sessions to have invited and regular speakers to report on the synthesis of research findings gained in Amazonia during the last three decades. Leading and junior scientists from Brazil, the United States, other South American countries, and Europe who have played pivotal roles in experiments and numerical studies scientists will be invited to make oral presentations. The planned conference sessions will offer an unprecedented and historical opportunity for research leaders from various Amazonia projects to gather at a single venue. Dr. Carlos Nobre, a very well know Brazilian atmospheric scientist, has been preliminary contacted about the planned conference sessions. He has expressed interest in giving a plenary presentation on the theme related to “The legacy of the Amazonian research project (LBA) and future directions for climate change issues”. Because the planned conference sessions will be part of centennial celebrations of the American Meteorological Society, it is expected numerous speakers will accept the invitation to partake in the conference sessions.
