Johannes Gutenberg University, Mainz, Germany




Our understanding of the global UTLS has significantly advanced in the last years by new observational data sets and model results. However, deficiencies of our current understanding of the various processes affecting the UTLS composition and dynamics over a broad range of scales still exist. Particularly, coupling and feedback mechanisms between the broad range of processes introduce large uncertainties to quantitative estimates of future changes on the UTLS and surface climate. As a continuation of a number of UTLS focused SPARC workshops (Bad Tölz 2001, Mainz 2005, Boulder 2009), this workshop will bring together experts from different fields of UTLS research. This involves observational and model-based studies as well as theoretical analyses from the local to the global scale.

The workshop aims to 1) summarize the current state of UTLS research, 2) identify the gaps of scientific understanding, and 3) guide the development of future research strategies.

Scientific themes

  • Composition and trends in the UTLS

  • Transport pathways and source regions

  • Clouds and aerosols

  • Circulation changes and dynamical processes affecting the UTLS

  • Coupling mechanisms between composition and dynamics

  • Uncertainties and future tasks
