The UKESM project is structured into 5 Research Themes:
RT1 finalises development and release of UKESM1, including user support. RT1 will also carry out CMIP6 experiments that form the basis for the science objectives of the project.
RT2 emphasizes evaluation of UKESM1, performed both at the process-level (RT2.1), and for the fully coupled ESM (RT2.2).
RT3 emphasizes scientific analysis of Earth system projections, including investigation of emergent constraints to reduce uncertainty in future feedbacks.
RT4 develops the component models for future UKESM.
RT5 targets improvement of fully coupled versions of UKESM.
