In this chapter of the Future Vision for Atmospheric Chemistry, we will discuss the key issues for future research in the stratosphere and mesosphere. Through the following six sections, we will propose a scope for the next decade and discuss in detail research directions that should be developed.
(1) Coupling/mass exchange between the troposphere and the stratosphere
(2) Impacts on stratosphere/mesosphere by changes in atmospheric circulation due to climate change
(3) Contemporary problems of ozone layer from the viewpoint of both ozone depletion and climate change
(4) Effects on the stratosphere and mesosphere caused by the changes of solar activity and physical condition of magnetosphere and ionosphere
(5) Key issues and instrumental development for the stratosphere/mesosphere to be studied by ground-based and/or balloon observations
(6) Key themes in the stratosphere/mesosphere to be clarified by satellite observations
