Climate and Cryosphere encourages CliC-affiliated tasks and activities to consider submitting a proposal and/or using BACO-25 for business and activity meetings. If you’re interested in receiving financial support from CliC to attend BACO-25, please contact us at

The International Association of Cryospheric Sciences cordially invites you to submit symposium proposals for the Busan IAMAS-IACS-IAPSO Joint Assembly 2025 (BACO-25) until 1 March 2024. 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.

Proposals for individual symposia are invited on topics within the remits of the International Association of Meteorology and Atmospheric Sciences, the International Association of Cryospheric Sciences and the International Association for the Physical Sciences of the Oceans, and for joint symposia concerning interactions between two or three of the atmosphere, cryosphere and ocean.

Symposium proposals (maximum 300 words) should include:

  • Session title
  • Session topic
  • Proposal type: IACS symposium, or joint symposium with IAMAS and/or IAPSO
  • Number of conveners
  • Convener information: Name, affiliation, email address, country
  • Expected number of presentations (can be adjusted later depending on room availability and number of abstracts received)

Proposals will be considered on their scientific merits, significance of their themes and overall programme balance. Symposia may be aggregated before being included in the final programme. We strongly encourage diversity and the involvement of young scientists as conveners.

Please submit symposium proposals by email to Richard Essery, IACS Secretary General
