"Quantifying the exchange, or “flux”, of atmospheric acids between the air and the Earth’s surface is important for understanding atmospheric chemistry, ecosystem inputs and pollutant deposition. These processes directly impact human health and environmental change. This PhD studentship will make new measurements of atmospheric chemicals with a chemical ionisation mass spectrometer (CIMS) as part of national and international experiments in order to test these hypotheses: 1. Inorganic atmospheric acids make a significant contribution to the acid dry deposition component of input to European sensitive ecosystems. 2. Agricultural point source emissions are a significant source of organic acids to the UK atmosphere. 3. Sensitive upland ecosystems are subjected to higher acid inputs than lowland areas because they remain more closely coupled to the atmosphere above. 4. Atmospheric acids do not always deposit at the maximum rate permitted by turbulence, as suggested by current deposition parameterisations. 5. Heterogeneous processes on vegetation surfaces and urban areas provide a significant daytime source for HONO and organic acids. The studentship is based at CEH Edinburgh, supervised by Dr Christine Braban and Dr Eiko Nemitz. CEH Edinburgh is close to the Pentland Hills south of Edinburgh. The student will be registered and academically supported by Dr. Carl Percival at the University of Manchester. CEH and the University of Manchester are committed to a high quality graduate training programme to ensure that the successful candidate has opportunities to develop their career, skills and experience. The successful candidate will be trained in mass spectrometry, field work, meteorology, data acquisition and analysis, UK and European environmental science and policy. The PhD would be suitable for final year or Master's level science students, or mature students. More details are details are on http://www.findaphd.com/search/ProjectDetails.aspx?PJID=36315. The deadline for applications is the 27th January 2012. Please contact Christine Braban (email@example.com<mailto:firstname.lastname@example.org>) for more details" Christine Braban Environmental Physicist CEH Edinburgh Bush Estate, Penicuik EH26 0QB 0131 445 8482 email@example.com http://www.ceh.ac.uk/StaffWebPages/DrChristineBraban.html
