"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  The deadline 
for applications is the 27th January 2012. Please contact Christine Braban 
(<>) for more details"
