The Energy Environment Research Centre attends the 2024 ACTRIS Scientific Conference
The Energy Environment Research Centre attends the 2024 ACTRIS Scientific Conference, held in Rennes from 13-16 May 2024 at the Convent of the Jacobins
The European Aerosol, Cloud and Trace Gases Research Infrastructure (ACTRIS) produces high-quality data and information on short-lived atmospheric constituents and on the processes responsible for the variability of these constituents in natural and controlled atmospheres.
The second ACTRIS scientific conference (and first in-person event) was organised to bring together members of various atmospheric science communities to discuss the latest scientific advances in the field of air quality and climate research and the related health effects.

The four CERI EE researchers who attended the event – Joel Brito, Véronique Riffault, Thérèse Salameh and Stéphane Sauvage – presented a wide range of work resulting from long-term observations and intensive campaigns related to thesis projects (Hasna Chebaicheb, Aliki Christodoulou, Marvin Dufresne, and Shouwen Zhang), collaborative national and European projects (including work from LCSQA and the latest intensive campaigns conducted by ACROSS and EMEP), and of course from their strong involvement in the ACTRIS research infrastructure.
This resulted in no less than 10 oral presentations for which we were first authors (in bold) or co-authors and 2 poster presentations, as follows:
ORAL PRESENTATIONS
- Nora Nowak et al., Towards a better understanding of atmospheric carbon in the free troposphere
- Max Gerrit Adam et al., First ACTRIS intercomparison for nitrogen oxides (NOx) at Research Centre Jülich
- Wenche Aas et al., Intensive measurement of VOCs and organic tracers during the summer heat wave 2022
- Thérèse Salameh et al., Is traffic still an important source of Volatile Organic Compounds in European urban areas?
- Prodip Acharja et al., Wildfire plumes in the Paris region (France) during 2022 showcase the much-needed interconnections between ACTRIS and ICOS observations
- Ludovico Di Antonio et al., Aerosol spectral complex refractive index and single scattering albedo in the Paris urban area and its suburban and forested surroundings during the ACROSS field campaign: variability and constraint for direct radiative effect estimation in regional models
- Hasna Chebaicheb et al., Multi-year high-time resolution datasets of submicron aerosols at 13 French urban sites: Chemical composition and organic aerosol source apportionment
- Mariana Farhat et al., Emissions and chemistry of industrial and non-industrial anthropogenic terpenoids by combining worldwide urban VOC databases over the last decade: insights from the DATAbASE project
- Michael Pikridas et al., Primary sources of submicron organic aerosol in the Eastern Mediterranean. How and why are they different from the rest of Europe
POSTER PRESENTATIONS

- Bachelier et al., Identification of instrumental artefacts in terpene detection: field studies and follow-up chamber campaign ACROSS-HECTIC
Involvement of IMT Nord Europe in ACTRIS
Since 2013, IMT Nord Europe has been involved in various European projects that led to the creation of the ACTRIS research facility, including as part of the European Topical Centre for Reactive Trace Gases In Situ Measurements (CiGas) along with five other European partners. The key mission of CiGas is to provide scientific and operational support to ACTRIS National Facilities (NFs), observation and exploratory platforms (GAW, EMEP networks), which conduct continuous long-term measurements of volatile organic compounds (VOCs), highly oxygenated organic molecules (HOM) and nitrogen oxides (NOx). IMT Nord Europe’ contributions to CiGas supports national VOC monitoring strategy as part of LCSQA by assisting AASQA with the implementation of means of measurement, validation and use of the data.
Since 2016, IMT Nord Europe has also been operating the Atmospheric Observatory of Lille (ATOLL) platform in collaboration with the Laboratory of Atmospheric Optics (LOA, ULille / CNRS). The platform comprises measurements of the physical, chemical and optical properties of aerosols by using surface-level situ techniques and remote sensing. At the end of 2023, the European Infrastructure Committee approved the request for initial certification of the site, thus recognising its compliance with the technical requirements and the commitment of the supervisory authorities. LCSQA also provides support in the measurement of the chemical composition of surface aerosols.
Moreover, IMT Nord Europe staff are also involved in the life and governance of the infrastructure, including (1) management of ACTRIS-France; (2) assistant management of the calibration centre for reactive trace gas (CiGas) and joint coordination of the national working group on the same topic; (3) joint coordination of the European technical and scientific forum bringing together all observation and exploratory platforms; and (4) coordination of a prospective working group on aerosol mass spectrometers.
All of this research work is integrated into Labex Cappa. The observation platform and the calibration centre are also supported by the State-Region Plan Contract for the Environment, Climate, Research and Innovation (CPER ECRIN – formerly CLIMIBIO).
