UK Earth System Model (UKESM)
UKESM is a JWCRP NERC/Met Office collaboration, pooling expertise and resources around a common Earth system model development and evaluation effort. UKESM has two overriding objectives:
To develop and apply a world-leading Earth system model.
To grow a community of UK ESM scientists.
The project runs from 2013-2021 and delivered the first version of the model, UKESM1 in February 2019. UKESM1 is being used for the UK's ESM contribution to the World Climate Research Programme's Coupled Model Intercomparison Project (CMIP6).
The model is available in a number of configurations for running different types of experiment:
The so-called AMIP configuration, in which the model atmosphere is forced by observed sea surface temperature and sea ice boundary conditions.
Two fully coupled configurations, which each make use of all model components:
- one set up to run the CMIP6 pre-industrial control experiment, and
- one to run the CMIP6 historical experiment.
There are also additional coupled configurations for the CMIP6 abrupt4xCO2 and 1%CO2 experiments, which can be created using the pre-industrial control experiment as a starting point.
The UKESM Long Term Science Multi-centre (LTSM) project is formed by the Met Office plus 8 NERC-supported centres: NCAS, BAS, BGS, CEH, CPOM, NCEO, NOC and PML.
