During oxidation reactions, O3 transfers its MIF signature to products, such as sulfates and
nitrates. In the past years, the MIF transfer between sulfate precursors, ozone and other oxidants
has been established (Savarino et al. 2000). The LGGE group has recently published the first
detailed investigation of MIF in the O3/NOx/NOy system [Savarino et al., 2008] and we will further
investigate such isotopic coupling in the laboratory. Laboratory experiments in atmospheric
simulation chambers will be performed both at the LGGE and CCAR where the interaction between O3
and NOx/NOy can be controlled, both in terms of pressure, temperature, concentration and light
flux, but also in terms of isotopic composition of the reactants. Isotopic anomaly transfers based
on specific oxidation reaction pathways will be established. From that point, we will quantify the
isotopic mass balance of oxygen atoms in nitrate and determine the statistical weight of each
atmospheric reaction pathways in collaboration with ESR project 3. The obtained result will be also
used to interpret natural samples and will provide important input for ESR projects 7 and 10.
Eligibility:
- Applicants must not already hold a PhD degree.
- At the time of selection for this position, you must be in the first four years (full-time
equivalent) of your research career. This is measured from the date when you obtained the degree
which would formally entitle you to embark on a doctorate, either in the country in which the
degree was obtained or in France.
- In line with EU requirements, successful applicants must demonstrate trans-national mobility,
i.e. they must move to France from their present country of residence. The project is not generally
open to applicants who are presently in France. Please check section II.1 of the FP 7 PEOPLE
Work
Programme for details.
Benefits:
This is a fully funded 3-year PhD project. Successful applicants will be paid a salary for three
years to cover their living expenses. In addition to conducting their research projects, they will
attend associated training modules that include summer schools, skills courses, scientific meetings
etc. They are also eligible for additional payments towards their travel and relocation costs as
well as a "Career Exploratory" allowance. Fellows will be able to start their three-year fellowships
from 1 September 2009 on.
How to apply:
- If you want to apply for this project, please follow the guidelines
here
- Applications must be received by 1 july 2009.
- Women researchers are particularly encouraged to apply.
- For further questions, please contact the supervisor of the project.
