The configurations listed here are those that are currently considered 'core' by the JULES management and science committees.

The UK Earth System Model
Get suite IDs Rosie Go by searching for "UKESM1" or "JULES-ES".
JULES-ES is the standalone version of the UKESM configuration: see suite u-bk886. JULES-ES is the current configuration used in the CMIP6 Earth System setup and supercedes:
- JULES-C (the original 'carbon cycle' config)
- JULES-C-1p1 (JULES-C with an improved seasonal cycle)
- JULES-CN (JULES-C-1p1 with the new soil biogeochemistry model)
Global Land vn9.0 (GL9.0). Please see the GA8.0 page linked to from here.
For coupled runs (i.e. used in conjunction with the Global Atmosphere (GA) configuration), see website for suite IDs or search Rosie Go for "GL9.0".
Note that the next GA/GL release (due to be frozen at the end of 2021) will be labelled as GAL9 and be explicitly designed as a coupled atmosphere/land configuration.

Note: From page 29 and fig 19 of Lock-et-al-2016-DiurnalKD16_v1.compressed.pdf regarding canopy height, UKV now requires all C3 grass to be 1.46 m tall (although this is currently being reviewed).
Note that inclusion in these tables is not intended to mean a configuration is necessarily 'recommended' for your particular use of JULES: these are configurations that have been tried and tested in particular situations and therefore should be consistent and accurate in those contexts, but you will have to assess for yourself whether it is suitable for your application of JULES. For example, in many operational configurations intended for the UM configurations are optimised for best results across ocean and sea ice surfaces as well as land surface, which means that they may not be as optimal as other configurations for land-only runs.
n.b. Because of the greater testing requirements for coupled configurations, and therefore correspondingly longer lead times for version releases, offline model setups will usually include more up-to-date science than their closest coupled counterparts. For benchmarking tests for some of these configurations, see the evaluation page.
