HyperFACETS

HyperFACETS (A framework for improving analysis and modeling of Earth system and intersectoral dynamics at regional scales) advanced the credibility and practical usefulness of regional climate information across the contiguous United States. Building on earlier DOE research efforts, the project brought climate scientists and stakeholders together to evaluate how well climate models represent the physical processes and extreme events that matter for real-world decisions.

The project combined process-oriented and event-based evaluation metrics, climate event storylines, and differential credibility analysis to characterize model strengths, biases, and uncertainties. Focusing on interactions among the atmosphere, water, energy, and land systems, HyperFACETS connected model evaluation with stakeholder needs in areas such as flooding, snowpack, extreme weather, and water resources. Its overarching goal was to make regional climate information both scientifically credible and useful for decision-making.
