[A-AS05] Stratosphere-troposphere Processes And their Role in Climate

Wed. May 29, 2019 9:00 AM - 10:30 AM 201B (2F)

convener:Yoshio Kawatani(Japan Agency for Marine-Earth Science and Technology), Shingo Watanabe(Japan Agency for Marine-Earth Science and Technology), Takashi Sekiya(Japan Agency for Marine-Earth Science and Technology), Kaoru Sato(Department of Earth and Planetary Science, Graduate School of Science, The University of Tokyo), Chairperson:Watanabe Shingo(海洋研究開発機構)

The Stratosphere-troposphere Processes And their Role in Climate (SPARC) is one of the
major projects of the World Climate Research Programme (WCRP), and is characterized
by its focus on chemical and dynamical coupling in the stratosphere and troposphere. In
this session, we welcome presentations on various processes in the stratosphere and tro
posphere.
