The tropical tropopause layer (TTL) is the dominant region for entry of tropospheric air into the global stratosphere. Despite significant theoretical advances and a rapidly growing archive of satellite data, important science questions related to the control of humidity and the chemical composition of air entering the stratosphere remain unanswered. Many processes are involved, including large‐scale ascent, atmospheric waves, and cloud microphysics. Further progress requires better analysis of current and past observations as well as new observational campaigns in which in situ observations on both balloons and aircraft platforms are coordinated with satellite observations.
