[Met-jobs] PhD Positions Available in Atmospheric Chemistry at Cambridge

From A Archibald <ata27@cam.ac.uk>
To met-jobs@lists.reading.ac.uk
Date Fri, 18 Nov 2016 13:54:46 +0000

PhD projects are now available through the NERC ESS DTP to study at the University of Cambridge. For full details on eligibility please see: http://essdtp.esc.cam.ac.uk/prospective-students/funding-information

Within the Department of Chemistry we are offering a range of topics:

Air Pollution Human Health and Monitoring 
--------------------------------------------------------------------------
APID: Air Pollution Improvements for Delhi - Prof. Rod Jones and Dr Alex Archibald
APID will understand the complex role of different sources of emissions on the burden of pollutants in Delhi and use a numerical model to derive ways in which to improve air pollution in the region.

Understanding Air Quality in a Chinese Megacity. Prof. Rod Jones and Dr Alex Archibald
The student will evaluate a new generation of low cost high quality air quality monitoring instruments and use these instruments to produce a highly vertically resolved data set of air pollutants from the IOP tower in central Beijing.

Health-Relevant Air Pollution Measurements. Prof. Markus Kalberer and Prof. Rod Jones
The student will take active part in field studies in the UK and potentially abroad where they will operate a new Reactive Oxygen Species (ROS) instrument and collect aerosol samples for further analysis in the lab.

Atmospheric Aerosol Particle Composition Affecting their Climate and Health Effects. Prof. Markus Kalberer
The student will generate atmospheric aerosols using the large-scale Cambridge Atmospheric Simulation Chamber, which allows to mimic atmospheric processes under realistic ambient conditions. A range of state-of-the-art mass spectrometers will be used to characterize organic aerosol and gas phase composition and formation processes. The simultaneous analysis of gas and particle components with unprecedented time resolution and sensitivity will allow to study in detail the fast gas/particle transition processes that lead to particle formation in the atmosphere. A range of atmospherically relevant formation processes will be studied to simulate natural and anthropogenic particle sources and assess their importance in the atmosphere.

Greenhouse gas emission monitoring using low cost sensor networks. Prof. Rod Jones and Prof. Neil Harris (Cranfield)
The student will undertake analysis of existing and new CH4 data from the East Anglia network, including measurement and data analysis including Bayesian inversion techniques and the Met Office NAME InTem model.

Fundamental aerosol and gas phase chemistry
--------------------------------------------------------------------------
ROAR: Reactions of Organic Atmospheric Radicals – a combined experimental and modelling study. Prof. Markus Kalberer and Dr Alex Archibald
The student will perform laboratory experiments to characterise and quantify Criegee Intermediate formation and reaction rates from several important atmospheric alkenes such as isoprene and terpenes with key atmospheric trace gas such as water, NO2 or SO2 and other volatile organic compounds. The student will then integrate these experimental results into atmospheric reaction schemes within the UKCA model, the UK community chemistry-climate model developed in Cambridge and a processes box-model to explore the full sensitivity of the complex chemical system.

Earth System Science 
--------------------------------------------------------------------------
CONTEST: Feedbacks between COmpositioN and climate in The Earth SysTem. Dr Alex Archibald
The student will use the new UK earth System Model (UKESM-1) to study composition-climate feedbacks, validating the model results against a wide array of observations from satellites, aircraft and in situ observations.

The global methane budget. Prof. John Pyle and Dr Alex Archibald
You will contribute to an improved understanding of the methane budget by combining new measurements of methane, and its isotopes, with numerical modelling.  The new data will come from field projects in which the project supervisors are involved, and in which you will play a role.

The Polar Atmosphere under Global Climate Change. Prof. John Pyle, Dr Alex Archibald and Dr Anna Jones (BAS).
The student will consolidate various polar tropospheric composition datasets, to develop a time-varying (seasonal to longer, depending on the particular data) picture of polar composition and its recent changes. Our global composition climate will be run, first, to allow comparison between the model, as a representation of our best current understanding, and the data. hen a series of integrations will explore polar composition change, under a range of assumptions about climate change and inferences made about the best means of early detection of future change.

The last great ozone destroyer. Prof. John Pyle and Dr Alex Archibald
The student will run a series of experiments using an established chemistry-climate model, based on the Met Office climate model, to which we have added chemistry schemes. The project will involve the design of the experiments and detailed analysis of the large volumes of data produced. Types of experiments might include investigation of the sensitivity of the ozone/climate system to size and geographic location of emissions.

INCAZ: Impacts of changes in North Atlantic Climate And oZone. Dr Alex Archibald
The student will use a new Earth system model, UKESM-1, to study composition-climate interactions, validating the model results against a wide array of observations from satellites, aircraft and in situ observations collected on-board the UK research aircraft (www.faam.ac.uk). They will perform a series of experiments that perturb ozone precursor emissions as well as physical climate/processes.

VHALS: Volcanic sources of Halogens And their cLimate impactS. Dr Alex Archibald, Dr John Maclennan and Dr Marie Edmonds.
The student will work alongside both Earth and atmospheric scientists. Geochemical data extracted from lavas in a range of flood basalt provinces will constrain a series of model experiments that will probe volcanic halogen emissions. The student will learn how to perform these model experiments using a state of the art chemistry-climate model.
