The UKESM project works closely with other NERC Long-term Science, Multi-centre (LTSM) projects concerned with global climate and Earth system change. In particular:
ACSIS(climate processes and predictability over the North Atlantic),
ORCHESTRA(carbon and heat uptake in the Southern Ocean) and
LOCATE(developing estimates and understanding of terrestrial carbon fluxes into the ocean).
Collaboration focuses on the provision of UKESM1 models and simulation data to these projects for advanced scientific analysis and conversely, the use of observations and process-understanding developed in these projects for analysis of UKESM1 and development of UKESM2.
We work closely with the Horizon 2020 projectCRESCENDO, coordinated by the UKESM coordinator. CRESCENDO involves 7 European ESMs targeting improved representation and evaluation of biogeochemical and aerosol processes in ESMs.
We collaborated with the H2020 projectPRIMAVERA(coordinated by MOHC) investigating the benefits of increased resolution in physical climate models, with project findings guiding the planning of UKESM2.
International collaboration is also through established links focusing on key CMIP6 experiments. Such cooperation facilitates the sharing of models, evaluation metrics and data sets, which helps to increase the productivity of the UKESM project.
Science and research themes
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.
Planned resolutions of UKESM1:
UKESM1-N216ORCA025: 60km atmosphere, ¼° ocean
UKESM1-N96ORCA1: 130km atmosphere, 1° ocean
The following diagram shows how the research themes contribute to the development of the UK Earth System Modelling project and collaboration with other relevant organisations.
