Arctic PASSION will address the urgent need for coordinated and accessible Earth observation and information services for the Arctic region. The key motivation behind Arctic PASSION is the co-creation and implementation of such a coherent, integrated Arctic observing system: the ‘Pan-Arctic Observing System of Systems – pan-AOSS’. It aims to overcome known flaws in the present observing system by refining its operability, improving, and extending pan-Arctic scientific and community-based monitoring and the integration with Indigenous and Local knowledge, by streamlining the access and interoperability of Arctic Data systems and services, and by ensuring the economic viability and sustainability of the observing system for years to come.
