The Arctic Observing Summit (AOS) is a high-level, biennial summit that aims to provide community-driven, science-based guidance for the design, implementation, coordination and sustained long-term (decades) operation of an international network of Arctic observing systems. The AOS provides a platform to address urgent and broadly recognized needs of Arctic observing across all components of the Arctic system, including the human component. It fosters international communication and the widespread coordination of long-term observations aimed at improving understanding and responding to system-scale Arctic change.
The 5th biennial AOS will be held as part of Arctic Science Summit Week (27 March – 2 April 2020). The theme of AOS 2020 is "Observing for Action". The AOS fosters communication and international collaboration and coordination of long-term observations aimed at improving understanding of and response to system-scale Arctic change. The AOS is an international forum for optimizing resource allocation, and minimizing gaps and duplication, through coordination of and exchange among researchers, agencies, Indigenous Peoples, non-governmental organizations, the private sector and others involved or interested in long-term observing activities. The AOS serves as a platform to identify and address societal and scientific needs and priorities, minimize gaps in data and information, reduce duplication, improve coverage and breadth, and contribute to solution-based applications and knowledge sharing.
