The international initiatives CATCH, PACES, BEPSII, ASPeCt and QUiesCENT will hold a joint meeting bringing together scientists with an interest in atmosphere-ice-ocean research focussing on chemical, biogeochemical and physical processes in the Arctic and Antarctic and links to climate change. Cold regions which are seasonally or permanently covered by snow and ice, notably the Third Pole, are also of interest. The primary objective of this meeting is to strategize for the 5th International Polar Year 2032 planning workshop scheduled to take place in Aussois, Alps, France, in November 2024.
