v3/v4 Campaign Goals

Targeted for use in Phase 3, E3SM versions v3 and v4 will feature notable developments in advancing the fully-coupled E3SM to answer the more demanding questions in the corresponding science campaigns. Advancing better simulations requires the performance expected from the Exascale systems planned for DOE centers.


E3SM v3/v4 science drivers and science questions

The v3/v4 science drivers and science questions focus on addressing uncertainty in predicting future changes in

  • Water cycle changes and impacts
  • Human-Earth system feedbacks
  • Polar processes, sea-level rise, and coastal impacts


See Sceince Drivers for the details.
