The SAGE department (Sciences of the Atmosphere and Environmental Engineering) at IMT Lille Douai is organizing and hosting the annual workshop for the European ACTRIS–WP3 project on atmospheric reactive trace gases. The ACTRIS (Aerosol, Cloud and Trace Gases Research InfraStructure) project concerns the construction of a research infrastructure for Atmospheric Sciences and more particularly the environmental challenges of atmospheric pollution and climate change.
