Post-doctoral Position in Atmospheric Chemistry en Cdd 12 Month at Imt Nord Europe

**Discipline**:Atmospheric Chemistry

**Line Manager**:Alexandre TOMAS / Sébastien DUSANTER

**Workplace**:Bourseul site, Marie Curie building

**Type of contract and duration**:fixed-term contract, 12 months

**CONTEXT**:
Public establishment belonging to IMT (Institut Mines-Télécom), placed under the supervision of the Ministry of Economy, Finance and Industrial and Digital Sovereignty, IMT Nord Europe has three main objectives: providing our students with ethically responsible engineering practice enabling them to solve 21st century issues, carrying out our R&D activities leading to outstanding innovations and supporting territorial development through innovation and entrepreneurship. Ideally positioned at the heart of Europe, 1 hour away from Paris, 30 min from Brussels and 1h30 from London, IMT Nord Europe has strong ambitions to become a main actor of the current industrial transitions, digital and environmental, by combining education and research on engineering and digital technologies.

Located on two main campuses dedicated to research and education in Douai and Lille, IMT Nord Europe offers research facilities of almost 20,000m² in the following areas:

- Digital science,
- Processes for industry and services,
- Energy and Environment,
- Materials and Processes

The post-doctoral work will be carried out in the frame of a collaboration between the Atmospheric Sciences and Environmental Engineering research unit (SAGE) of CERI EE and the department of Atmospheric Sciences of the National Central University (NCU) in Taiwan.

SAGE has ongoing research activities focusing on atmospheric chemistry, air quality and the impacts of human activities on the composition of the atmosphere. It has currently a staff of about 50 people including 17 full-time faculty members. Research projects aim at a better understanding of the physical and chemical processes involved in the formation, transport and aging/transformation of gaseous and particulate pollutants in outdoor and indoor atmospheres.

**BRIEF**:
The activities that will be carried out during this post-doctoral 1-year period at CERI EE, IMT Nord Europe, are part of the French-Taiwanese bilateral project ‘Tropospheric **O**zone in **S**outh **E**ast **A**sia: Budget and **M**itigation **S**trategies (OSEAMS)’ funded by the French national research agency (ANR) and the National Science and Technology Council from Taiwan (NSTC). This project aims at understanding ozone sources and sinks in the South-East Asia region and developing mitigation strategies to reduce ozone concentrations and impacts.
- Provide a detailed description of the ozone-forming chemistry occurring in Taiwan,
- Investigate how this chemistry has evolved over the past three decades in response to mitigation measures.

Experiments will be performed in a large atmospheric simulation chamber (9 m3) equipped with state-of-the-art instrumentation (PTR-ToF-MS, online GC-MS/FID, O3 and NOx analyzers,). The chemical composition of representative urban & suburban air masses observed in Taiwan over the past 3 decades will be reproduced in the chamber. The ozone-forming chemistry will be thoroughly investigated, with a focus on assessing the sensitivity of ozone production to NOx and determining the ozone formation regime (whether NOx-limited or NOx-saturated). These chamber experiments will be interpreted using 0-D models, implementing current state-of-the-art chemical mechanisms such as the Master Chemical Mechanism (MCM), to evaluate the reliability of these mechanisms to describe O3 formation in Taiwan.

The recruited post-doctoral fellow will be supported by an engineer who will assist with the operation of the chamber and instrumentation. This work is expected to result in both a scientific publication and a presentation at an international conference.
