Our session “Dynamics and chemistry of the upper troposphere and stratosphere: observations and models” is a long-running element of the AS programme. As in previous years we invite presentations that cover the whole spectrum of upper tropospheric and stratospheric composition-climate interactions research. We are looking forward to hear about new measurements (using in-situ or remote sensing methods) and their interpretation and about new modelling studies (using a range of different models) trying to understand composition-climate interactions.
We have two solicited speakers:
Valerie Thouret: MOZAIC-IAGOS program: 20 years of in-situ data in the UTLS
Jörn Ungermann: On the observation of climate-relevant processes in the UTLS
