October 13, 2022 In the International Aerosol Conference 2022 held in Athens, the AEROMET II EMPIR project had three dedicated sessions. Firstly, a dedicated training session consisting of 6 lectures to help to disseminate the practical knowledge contained within the project’s consortium. Secondly, a dedicated poster session of 9 posters detailing the work already completed within the project. Finally, a dedicated presentation session containing 6 presentations in a room containing 150 attendees. This allowed the project partners to showcase the work within the project and take questions about the work conducted and future aims of AEROMET II. The dedicated sessions are listed below.
