Welcome all,

On behalf of all members of IAMAS, IAPSO and IACS, we are delighted and honored to host IAMAS-IACS-IAPSO Joint Assembly 2025 in Busan, Republic of Korea. I am Kyung-Ja Ha, the Chair of the Local Organizing Committee and the professor of the Department of Atmospheric Science at the Pusan National University.

Busan IAMAS-IACS-IAPSO Joint Assembly 2025 will be held from July 20 to 25, 2025. The 6-day event will attract distinguished colleagues from academia, government, and industries from around the globe, who will participate in scientific presentations and discussions, exchanges of information, and international cooperation on earth sciences. Participants at this prestigious global gathering will enjoy exceptional scientific programs, exhibitions, and exciting support events.

Busan is the second largest city in Korea known as an ocean tourism city with 7 beautiful beaches. It is also a city of festivals, holding festivals and events all year round, including the Busan International Film Festival, one of Asia’s most prestigious film festivals, and Busan International Fireworks Festival. The close proximity to UNESCO World Heritage designated treasures in Gyeongju, along with the beautiful resort of Jeju, which lays just a short flight from Busan, are just some of the unique experiences for international delegates to enjoy.

We sincerely hope to have the opportunity to welcome you to Busan in 2025.
