Identifying actionable improvements to the national and pan-Arctic observing system

The United States Arctic Observing Network (US AON) is a collaboration-based initiative that promotes well-defined networks of sustained Arctic observations through partnership development and the advancement of shared planning processes and methods (e.g. Value Tree Analysis, VTA) within NOAA, across US Federal agencies and with other partners, nationally and internationally. The project aims to provide cross-agency coordination for federal efforts related to sustained Arctic observing in order to unify various Arctic observation efforts. This coordination is guided by the US AON Board (Federal-only funders), co-chaired by NOAA, NSF and NASA, with participation from DOI, DOE, EPA and DOD. Organizationally, US AON is the observing focal point of the Interagency Arctic Research Policy Committee (IARPC), which is charged by Congress to coordinate all Federal agencies engaged in Arctic research. This initiative also advances the international Roadmap for Arctic Observing and Data Systems (ROADS) through Sustaining Arctic Observing Networks (SAON), and promotes partnership and community building. A fully developed US AON will promote collaborative use of Arctic research and operational products in order to fully understand the Arctic and Earth system in support of discovery and key public services. 

A sample of a Value Tree Analysis (VTA) for the ARC2020, in support of Fundamental Understanding of Arctic Systems. Observing system value in support of the seven ARC Vital Signs propagates forward (left to right) through observation and model-derived data products, then Vital Signs to societal benefit. Color coding indicates a performance score for nodes (see insert), averaged across all uses; links are weighted (indicated by line thickness) based on their criticality to downstream value. The VTA indicates the Vital Signs were most relevant to the IAOAF Societal Benefit Area (SBA): Fundamental Understanding of Arctic Systems (composite score = 74), but also provided value to SBAs like Environmental Quality (not shown, 59) and Marine and Coastal Ecosystems and Processes
