Busan IAMAS-IACS-IAPSO Joint Assembly 2025 (BACO-25)

The International Association of Cryospheric Sciences (IACS) will hold its next assembly as a joint assembly with the International Association of Meteorology and Atmospheric Sciences (IAMAS) and the International Association for the Physical Sciences of the Oceans (IAPSO). The IAMAS-IACS-IAPSO Joint Assembly 2025 (BACO-25) will be held from 20-25 July 2025 at the Busan Exhibition and Convention Center (BEXCO) in Busan, Republic of Korea. The six-day event will bring together atmosphere, cryosphere and ocean scientists from around the globe to participate in scientific presentations and discussions, exchanges of information, and international earth science cooperation. All participants are required to follow the IUGG Code of Conduct.

Travel grants will be available for attending the meeting. Details will be announced in late 2024. See general information on grants here.

The scientific program will include IACS sessions on the cryosphere and cryosphere-related symposia joint with IAMAS or IAPSO associations. IACS will have an open plenary meeting for its members and correspondents. IACS working groups, standings groups, joint commissions and bodies can request rooms for splinter meetings during the assembly. IACS highlights will also include IACS keynote Union Lecture (TBD) and Graham Cogley awards for student oral and poster presentations.
