Postdoctoral Research Associate

Modelling secondary organic aerosol formation

The Department of Environmental Science and Technology has an opening for a
postdoctoral research associate, based in the Environmental Measurement
Modelling and Assessment (EMMA) Group, at the Silwood Park Campus in Ascot.
This 27 month full time position will contribute to the NERC Polluted
Troposphere project, Tropospheric Organic Chemistry Experiment (TORCH).

Organic matter often makes a significant contribution to, and sometimes
dominates, the composition of submicron aerosols in the troposphere. A large
proportion of the organic content is believed to result from the
gas-to-aerosol transfer of semi-volatile and involatile products of the
oxidation of emitted gas phase organics, and is therefore classed as
secondary organic aerosol (SOA). Owing to the wide variety of emitted
organic compounds and the complexity of their oxidation mechanisms, the
organic composition of SOA is highly complex. The objectives of this study
are to develop and implement a description of the gas-aerosol partitioning
of oxidised organic compounds for application to the large number of species
generated in the Master Chemical Mechanism (MCM). The resultant mechanism
will be applied to the interpretation of field measurements of gaseous and
aerosol phase organics, made as part of the TORCH project.

Applicants should have a PhD in the field of atmospheric chemistry and a
physical chemistry background. Preference will be given to applicants with a
sound understanding of tropospheric chemical processes and experience in
model development and application.

Salary will be in the RA1A range of 18,265-27,339, depending on age and
experience.

Enquiries and requests for application forms should be directed to Dr Mike
Jenkin, Department of Environmental Science and Technology, Imperial College
London, Silwood Park Campus, Ascot, SL5 7PY (e-mail: [email protected] ),
quoting ref MEJ03/1.

Closing date : 30 April 2003

Postdoctoral Research Associate

Gas phase tropospheric chemistry of organic compounds

The Department of Environmental Science and Technology has an opening for a
postdoctoral research associate, based in the Environmental Measurement
Modelling and Assessment (EMMA) Group, at the Silwood Park Campus in Ascot.
This two-year full time position forms part of the Department of the
Environment, Food and Rural Affairs (DEFRA) research programme on Modelling
of Tropospheric Ozone Formation.

A rigorous description of the oxidation of emitted organic compounds is a
central component of research and policy models used to describe the
formation of ground level ozone. The objectives of this study are to develop
and validate explicit and simplified mechanisms for a series of complex
anthropogenic and biogenic organic compounds known to be emitted into the
atmosphere. The mechanisms will contribute to the wider development of the
Master Chemical Mechanism (MCM) and the Common Representative Intermediates
(CRI) mechanism, and will be applied in tropospheric models to assess the
role of organic compounds in the formation of ground level ozone and other
secondary pollutants.

Applicants should have a PhD in the field of atmospheric chemistry.
Preference will be given to applicants with a sound understanding of
tropospheric chemical processes and with some experience in model
development and application.

Salary will be in the RA1A range of 18,265-27,339, depending on age and
experience.
