		| Scope | 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 mesosophere. |
