Research community configurations


Here is a selection of JULES research community configurations. These configurations are intended for use by the JULES development and research community (they have been academically published and also approved for use by the relevant JULES module leaders), and are maintained on an ad hoc basis rather than routinely (and are not guaranteed bit-comparable between JULES versions). If you are aware of a widely-used configuration that is not included here, then please send me the details (see email address below) - either in Rose suite format or as a set of namelists (along with a version number of the version of JULES for which they are appropriate) (see here for all configurations):

(AM = Alberto Martínez de la Torre at CEH Wallingford)

Global Water Resources Reanalysis 2 (WRR2) (see 2014 E2O newsletter here)Hydrology

This configuration results from work at CEH to find the best JULES hydrology options for GB under the UKEP project (Martínez-de la Torre et al., in prep.) and its extrapolation for global applications under the earth2observe project. The main difference with other configurations is the use of a new development to include a terrain slope dependency in the saturation excess surface runoff production scheme (see jules_hydrology and jules_pdm namelists). This development has been part of the trunk since JULESvn4.9.

An iLAMB evaluation exercise of this configuration together with the core configurations is available here.



AM's suite for use with JULESvn4.5 and WFDEI data: u-ai199.

(Note: This suite uses WFDEI 3-hourly driving data, with 'nb' temporal interpolation flag SWdown and LWdown, and 1 hour timestep (as it is set up for daily and monthly outputs). Please see note about WFDEI data here for other options)

A JULES-IMOGEN configuration has also been developed by Eddy Comyn-Platt for the CLIFFTOP project (see slide 7 here), designed to use the most up-to-date carbon cycle features available in JULESvn4.8.

JULES-C2: u-aa458

Please 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 on land-only runs.
For benchmarking tests for some of these configurations, see the evaluation page. Finally, many other configurations are in use in the community (on the Rosie Go database), but these are not intended for wide, general use.
