AQ-Watch partners are coming to Hamburg to attend the project kick-off meeting on 11-12 February. This meeting will not only serve for partners to get to know each other, but it is also an opportunity to discuss specific activities and make progress on approaches on the science and innovation. Prof Guy Brasseur, from the Max Planck Institute for Meteorology and AQ-Watch Coordinator, will lead the discussions. Leaders of each of the Work Packages (WP) will make presentations with the objectives, tasks and deliverables of each WP, as well as discussing the interactions among partners. A meeting report will be prepared and made available after the meeting takes place.
