2022 Model Hierarchies Workshop

The first Modeling Hierarchies Workshop, held in Princeton in November 2016, was framed around the question of exactitude in science.Since the time of that workshop, the modeling landscape has evolved considerably. For a second Modeling Hierarchies workshop, to be held at Stanford in August-September 2022 , the questions and themes of the first workshop return, but reflecting the concerns of the day: is the traditional GCM still useful, or has it run its course? Are digital twins really twins? Where lies the boundary between simulation and emulation? What does it mean for machine learning to be “inspired” or “guided” by physics? What role does a hierarchy of models play in our field?
