Arctic PASSION Pan-Arctic Observing System of Systems

In the Arctic the human-induced planetary warming already leads to changes that are faster here than anywhere else on our planet. They have environmental, societal, and economic impacts, locally and due to the Arctic’s role in the global climate system, far beyond the Arctic proper. This highlights the need for a sustained and accessible observing system that is tuned to the diverse needs of users, ranging from local inhabitants to academia through to industry and decision-makers.
