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
