drivers (how much do we know from empirical and first principles models); What are the limitations on our knowledge (e.g the physics of the transition from the mixed to diffusively controlled region); what limits the predictability of a region that sees the
transition from strong linkage to lower atmosphere tidal and wave forcing to a region driven by coupling to the magnetosphere, and what measurements and missions can systematically collect global data that provides inputs to assimilative models for global
scale nowcasts and the first-principles models that most capture the physics and reproduce the observed behavior. We look forward to contributions from users community, empirical, assimilative and first principles modelers, ground- and space-based instrumentation
and commercial operators.</span><span style="color:#4472C4"><o:p></o:p></span></p>
