ENVIRONMENTAL SCIENCES SECURED-FUNDING STUDENTSHIP Chemistry-cloud-climate links in the Marine Boundary Layer
School: Environmental Sciences
Supervisor(s): Dr Roland von Glasow;
Application Deadline: 30th January 2009
Description:
This project has been pre-allocated funding from the School. FUNDING IS AVAILABLE FOR UK/EU STUDENTS. FUNDING AWARDED FOR THIS PROJECT WILL COVER TUITION FEES AND STIPEND FOR UK STUDENTS, TUITION FEES ONLY FOR EU STUDENTS. INTERNATIONAL STUDENTS WILL NOT BE ELIGIBLE FOR THIS FUNDING; THEY ARE STILL WELCOME TO APPLY FOR THIS PROJECT BUT WOULD HAVE TO FIND ALTERNATIVE FUNDING. Clouds have a profound effect on climate due to their ability to reflect sunlight back to space and thermal radiation back to the Earth. At the core of each cloud droplet there is a so-called cloud condensation nucleus (CCN) that determines the properties of the droplet. Many different types of particles act as CCN, each with different properties. The goal of this project is to improve our quantitative understanding of the bi-directional links between chemistry, the CCN population and stratiform clouds as well as between these clouds and climate (via so-called indirect aerosol effects). Our main interests are stratiform clouds in the marine boundary layer (MBL), how their microphysical and optical properties are affected by chemistry including gas-to-particle formation of new CCN and growth of CCN as well as how the clouds affect the chemistry in the MBL. Furthermore we will examine crucial steps of a widely publicised hypothesis of natural climate regulation (the “CLAW-hypothesis”). To this end the PhD student is supposed to use the Large Eddy Model, LEM, of the Met Office which will be extended as part of this project to include a simplified description of chemistry and the interaction with warm cloud microphysics. The use of the LEM will give us the opportunity to study whole cloud systems of scales of kilometres with high vertical and horizontal resolution. The results from these model runs will be compared with field data for example from the upcoming VOCALS-Rex campaign to be held in Oct/Nov 2008 in the southeast Pacific. The specific objectives of this studentship are: (1) To quantify the chemical processes that control new particle formation and particle growth in the marine boundary layer (MBL). (2) To quantify indirect radiative effects based on (1). (3) To quantify the impact of aerosol and cloud chemistry on the chemistry in the MBL.

How to Apply
Applicants should have or be expecting to obtain, a good honours degree (or equivalent) in a relevant subject. Applications are welcome all year round however early applicants will have a better chance of securing a place and a better chance of securing funding.
In addition to a completed application form you will need to submit the following:
Two completed reference forms (signed by the referee and stamped with the offical stamp of the institution at which he/she is employed).
University transcripts and a final degree certificate where appropriate.
Evidence of proficiency in English Language (e.g. IELTS or TOEFL certificate, for overseas students only)
Applicants for research degrees please also submit a completed Financial Guarantee Form.
For Research Degrees only:
Applications received by the stated deadline will be considered as part of a gathered field and applicants may be called for interview. Any projects not filled in the first round will be open again for applications in a second round. This process will continue until all advertised projects are filled.
Applicants who have not been successful in one round need not reapply.
