4th (AC)³ Science Conference on Arctic Amplification in Cologne

Our 4th (AC)³ Science Conference will take place in Cologne, Institute for Geophysics and Meteorology, Pohligstr. 3, from 23 - 26 February 2026.

We will also invite some members of our Scientific Advisory Board (SAB) to give keynote talks and to help us planning the final two years of (AC)³. The structure of the conference contains two parts. In Part I, specific scientific highlights of our research will be presented in three sessions focusing on aerosol particles, sea ice processes, and mixed-phase clouds. Part II will be organized in three sessions on the Strategic Questions (SQs) that we have promised to answer until the end of (AC)³. The program includes most importantly your contributions (oral or poster), and in addition renowned international keynote talks (SAB members), discussion panels, CCAs, an inspiring Monday evening talk, vibrant social events, and two poster sessions.

Active participation from all of you (including all subprojects) — whether by oral presentations or in poster sessions — is strongly encouraged to further develop the exciting research topics of the current project phase together. In particular, project PIs are invited to take the lead in guiding discussions and shaping outcomes in Part II.

The Call for Abstracts is now open until 5 December 2025. Please submit your abstract using the templates via the following link to Marlen Brückner. The conference booklet will be distributed to the participants at the registration both in hard-copy and electronic versions. The abstracts will not be published elsewhere.

The final program will be available by the end of 2025.
