IUGG & IACS General Assemblies


Next IACS Scientific Assembly

IACS-IAMAS-IAPSO Scientific Assembly in Busan, South Korea, 18-23 July 2021

[6 July 2020] It is with regret that IACS, along with the International Association of Meteorology and Atmospheric Sciences (IAMAS) and the International Association for the Physical Sciences of the Oceans (IAPSO), announce the cancellation of the BACO-21 joint assembly in Busan, Republic of Korea. The next time that IACS will meet in person will be at the IUGG 2023 General Assembly in Berlin. We thank the local organizers for their work and look forward to the possibility of a future meeting in Busan.

To fill the 18-23 July 2021 slot vacated by BACO-21, we will be hosting an online seminar series


Past IACS Scientific Assemblies

IUGG Assembly in Montreal, Canada, 8-18 July 2019

The 27th International Union of Geodesy and Geophysics (IUGG) General Assembly was held in July 2019 in Montréal, Canada. 2019 marks the 100th anniversary of IUGG. IACS hosted or co-hosted more than 30 symposia between 9 and 13 July, with a wide range of snow and ice topics. Waleed Abdalati, University of Colorado, USA, gave the prestigious Union Lecture in Cryospheric Sciences. See Full IACS Scientific Programme. Travel grants (in total ~11,000 Euros) were available especially to support students, early career scientists and attendees from less-affluent countries.


International Symposium on the Cryosphere in a Changing Climate in Wellington, New Zealand, 12-17 February, 2017.

IACS held its 2017 symposium at Victoria University of Wellington, New Zealand. This meeting brought together three of the leading international associations focusing on the cryosphere; the International Association of Cryospheric Sciences (IACS), the International Glaciological Society (IGS) and the Climate Cryosphere Project (CliC) of the World Climate Research Programme (WCRP). Andrew Mackintosh chaired the Local Organising Committee while Ian Allison chaired the Scientific Steering Committee. 250 delegates from more than 31 countries attended this conference. IACS provided ~10,000 Euro of travel grants to allow 17 early career scientists and scientists from developing countries to attend this meeting.
