Forwarded from CLIMLIST... Effect of “low-wind” circulation types on air pollution conditions in present and future climate Air pollutants (e.g., black and organic carbon, sulfur and nitrogen dioxide, other particulate matter, and ground-level ozone) are associated with substantial environmental and health impacts. They can also act as short-lived climate-forcing pollutants (SLCP) by affecting the earth's energy balance, and thus contribute to anthropogenic climate change. The impacts of these air pollutants strongly depend on their atmospheric concentration levels and lifetimes, which are governed by regional and local weather conditions. In particular, atmospheric conditions associated with low or no wind activity can lead to an accumulation of the air pollutants at the emission source and thus increase their health and environmental impacts. The goal of this project is to investigate the relationship between such atmospheric circulation conditions and the concentration and residence time of air pollutants, and thus air quality, in different regions under present climate conditions. Furthermore, it will be assessed whether these atmospheric conditions associated with health and climate impacts will change under future climate scenarios. The Ph.D. student will be involved in the activities of the SIWA teams working on air pollution and SLCP and will gain experience in working with Chemical Transport Models (CTMs), analysing observational data and model output, and combining knowledge from different fields, such as meteorology, atmospheric chemistry, climate change and air pollution. The Ph.D. student will work together jointly with Dr. Jana Sillmann and Dr. Tim Butler and will have the opportunity to participate in international research collaborations as part of this project. The Institute for Advanced Sustainability Studies e.V. (IASS) is an international, interdisciplinary centre of excellence located in Potsdam, financed by the Federal Ministry of Education and Research and the Federal State of Brandenburg, devoted to promoting science and research for global sustainability, particularly in the areas of climate change, the earth system and the development of new technologies and social pathways to sustainability. Candidates should have a degree in atmospheric sciences, physics, environmental sciences or related fields and advanced computer programming skills (UNIX, FORTRAN, R, etc.). Fluency in written and spoken English is required. Applications, including a brief statement of scientific background and interests, a curriculum vitae, and contact information of 2-3 references, should be send either in hard copy or by e-mail to: IASS, Institute for Advanced Sustainability Studies e.V. c/o Dr. Tim Butler Berliner Str. 130 14467 Potsdam E-Mail: <email@example.com> Applications submitted by June 30th, 2013 will receive full consideration, but position will remain open until filled. The IASS particularly encourages applications from female researchers; handicapped applicants will be given preference in case of equal qualifications.
