. In this paper we define the first Regional Atmosphere and Land (RAL) science configuration for kilometre-scale modelling using the Unified Model (UM) as the basis for the atmosphere and the Joint UK LandEnvironment Simulator (JULES) for the land. RAL1 defines the science configuration of the dynamics and physics schemes of the atmosphere andland. This configuration will provide a model baseline for any future weather or climate model developments to be describedagainst, and it is the intention that from this point forward significant changes to the system will bedocumented in the literature. This reproduces the process used for global configurations of the UM,which was first documented as a science configuration in 2011. While it is our goal to have a singledefined configuration of the model that performs effectively in all regions, this has not yet beenpossible. Currently we define two sub-releases, one for mid-latitudes (RAL1-M) and one for tropicalregions (RAL1-T). The differences between RAL1-M and RAL1-T are documented, and where appropriate we define how the modelconfiguration relates to the corresponding configuration of the global forecasting model.
