Institut für Umweltphysik COST 723 Fachbereich 1 Physik/Elektrotechnik „The Role of the UTLS in Global Change“ Altitude region around the tropopause is crucial for earths energy balance (water vapor cooling below, ozone heating above). Chemical, microphysical, and dynamical processes not well understood. Model and data studies for this altitude region. Assimilation as the central tool to consolidate models and observations. 3 Workgroups for the 3 areas. Common workshops for all workgroups. Stefan Bühler
Institut für Umweltphysik Fachbereich 1 Physik/Elektrotechnik WG 1: Measurement Techniques and Campaigns Gather data and make it available to the Action. Critically assess the weak links in our measurement capabilities, help to identify new techniques and platforms to strengthen them. Improve the use of satellite data by the EO community, help to assess new sensors. Evaluate measurement campaigns and help plan and promote new campaigns. Examples: Improved radiosonde calibration techniques, RT modeling efforts for improved satellite data usage. Stefan Bühler
Institut für Umweltphysik Fachbereich 1 Physik/Elektrotechnik WG 2: An Assimilated Ozone and Humidity Dataset Identify most relevant datasets of atmospheric constituents and other key parameters for UTLS. Develop and publish assimilation algorithms. Compute assimilated dataset and make it available. Quality control of observations and models. Analyze benefits of combining nadir and limb sounder information. Preliminary studies towards assimilation of instrument radiances from research satellites. Stefan Bühler
Institut für Umweltphysik Fachbereich 1 Physik/Elektrotechnik WG 3: Assessing the State of the UTLS and Understanding the Relevant Processes Assess UTLS climatology (mean state and variability). Assess trends where possible. Study dynamical processes in the UTLS and their role in global change. Quantify anthropogenic impact on the UTLS. Example for possible process studies: Connection of UTLS exchange processes to polar and subtropical jets. Stefan Bühler
