Atmospheric oxidation of the dominant emitted Hg(0) form is a key process whereby Hg from natural and anthropogenic sources is converted to more soluble and reactive Hg(II) species that will be deposited to ecosystems. Recent theoretical, field and experimental studies have proposed new atmospheric Hg redox pathways, including alternative oxidants, and direct photoreduction of Hg(II) forms. These new pathways need to be integrated in atmospheric Hg models and tested against observations of atmospheric Hg and oxidant dynamics.
To improve understanding of atmospheric Hg observations including the role of key oxidants, photoreduction and re-emissions.
Methodology & Expected Results
This project relies on previously made Hg observations, and on state of the art atmospheric Hg models. The spatial and temporal variability of Hg(0) and Hg(II) species concentrations along with some oxidants (BrO, NOx, O3) will be investigated in regions where high oxidation rates are observed or suspected (polar regions, high altitude sites, tropical regions). An improved understanding of Hg(0) re-emission sources (snow, sea-ice, ocean, land) and their role in the atmospheric Hg budget will be proposed using available 1D and 3D atmospheric models. Improvement of reactions schemes and parametrization of Hg(0)oxidation and Hg(II) reduction using the latest version of the models (i.e. GEOSChem 3D) will be tested in high oxidation environments, using recent UGA/CNRS data and GMOS, AMNET data. ESR1 will work in close collaboration with ESR2, 10 and 14.

Selin), 3 months, integrate novel field observations into global GEOS-CHEM 3D model; HZG (J. Bieser), 1 month, integrate novel field observations into 3D regional models, collaborate with ESR14.
GMOS-Train is looking for a broad international representation of early stage researchers. The network clearly acknowledges its responsibility for the recruitment of the researchers,
their working and living conditions, as stated in the document “The European Charter for Researchers - Code of Conduct for the Recruitment of Researchers”. Gender equality and
minority rights will also be promoted in the selection process. There is no age limit.
The positions are open to all nationalities. However, your application has to comply with the European Commission’s Mobility Rules, meaning that at the time of recruitment you must not have resided or carried out your main activity (work, studies, etc.) in the
country of the host organisation for more than 12 months in the 3 years immediately before the reference date (indicative start of the employment contract, Month Date 2020).
Compulsory national service and/or short stays such as holidays are not taken into account (European Commission’s Guide for Applicants).
Early-stage Researcher (ESR)
In case you have already gained prior work experience in academia, you shall be in the first four years (full-time equivalent research experience) of your research career at the
time of recruitment by the host organisation and have not been awarded a doctoral degree. Full-time equivalent research experience is measured from the date when you
obtained the degree entitling you to embark on a doctorate, even if a doctorate was never started or envisaged. Part-time research experience will be counted pro-rata (European
Commission’s Guide for Applicants).
Relevant University Degree
Master’s degree or equivalent in Environmental and Health Science or related fields.
In case an individual researcher is interested in several advertised ESR projects, he/she may apply for a maximum of three specific ESR projects and list their order
The selection committee will check applications against the following criteria:
- Scientific background and potential as indicated by candidate experience.
- Fit to a research project.
- Evidence of ability to undertake research.
- Evidence of working within groups or teams.
- Impact and benefit of the proposed training to the candidate’s research career.
Three candidates will be short-listed for each research project and invited to an interview (interviews by video link will be held if candidates are not able to travel).
Interviews will consist of two parts:
1) a short presentation by the candidate followed by questions and answers, and
2) competence-based interview.
