Arctic Observing Summit

The Arctic Observing Summit (AOS) is a biennial summit that aims to provide guidance based on the best available knowledge 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 foster international communication and the widespread coordination of long-term observations aimed at improving understanding and responding to system-scale Arctic change. It is an international forum for optimizing resource allocation through coordination and exchange among all involved or interested in long-term observing activities, while minimizing duplication and gaps.
