Welcome to the homepage of the
TP-Challenges International Conference
11-14 March 2024
Johannes Gutenberg University, Mainz, Germany

Objective

This conference took take place in cooperation with the DFG SFB TP-Change and SPARC

The upper troposphere/lower stratosphere (UTLS) region is important for global climate. Transient processes and small scale scale dynamics at the tropopause affect the distribution and gradients of radiatively active species, aerosols and clouds which in turn may feed back on dynamics.

The focus of the meeting was on UTLS processes and their feedbacks involving experimental research as well as theory and modeling. We aim at bringing together the expertise on tropopause relevant topics from different fields of research to discuss their relevance for the global atmosphere.

Invited Speakers:
Andrew Gettelman, Pacific Northwest National Laboratory (PNNL), Richland, USA, Christina Williamson,  Finnish Meteorological Institute and University of Helsinki, Finnland,  William Randel, National Center for Atmospheric Research (NCAR), Boulder, USA, Albert Hertzog, Ecole Polytechnique / IPSL, Cedex, France

Program Committee:
Peter Hoor, Joachim Curtius, Christiane Voigt, Ulrich Achatz, Peter Spichtinger, Andreas Engel, Holger Tost

Research Contributions will be organised into the three TPChange research areas:

• Research Area A - the role of aerosol and ice particles in the UTLS, their formation, chemistry, evolution and effect on the atmospheric radiation budget
• Research Area B - the interaction of dynamical and microphysical processes in the UTLS
• Research Area C - large scale processes and the impact of processes of all scales on UTLS composition and variability, their expected changes in the future and their impact on present and future climate
