[A-AS21_30AM2] Stratospheric Processes And their Role in Climate

Wed. Apr 30, 2014 11:00 AM - 12:45 PM 313 (3F)

Convener:*Kazuyuki Miyazaki(Research Institute for Global Change, JAMSTEC), Masakazu Taguchi(Aichi University of Education), Yoshio Kawatani(Japan Agency for Marine-Earth Science and Technology), Kaoru Sato(Department of Earth and Planetary Science, Graduate School of Science, The University of Tokyo), Chair:Masakazu Taguchi(Aichi University of Education)

The Stratospheric 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 based on both observations and modeling. In this session, we welcome presentations on various processes in the troposphere to the mesosphere.
