The HARMONIE-AROME model configuration in the ALADIN-HIRLAM NWP system

A document which describes the forecast model configuration (e.g. no data assimilation or EPS) used in our Reference System (Cy40h1) configuration. Accepted for publication in MWR:

It can be used as a baseline reference publication whenever you need to describe what the HARMONIE-AROME forecast model actually consists of.

HARMONIE-AROME configuration
The naming convention of our model and the other LAM models in the shared ALADIN-HIRLAM NWP system has had an extensive dialogue between the HIRLAM management group, the HIRLAM Advisory Committee (HAC) and the ALADIN Political Advisory Committee (PAC) as well as ALADIN/LACE partners. It has been adopted that the name 'HARMONIE-AROME' is to be used for the model configuration adopted in our Reference system from now onwards. This in recognition of the legacy provided by Meteo-France and ALADIN, but also indicating that the HARMONIE variant of AROME differs in specific aspects (described clearly in the paper above) from that of AROME-France. We hereby urge you (in writing proposals, scientific articles and conference presentations) to consistently use the naming convention "HARMONIE-AROME" when referring to our forecast model configuration.

HARMONIE scripting system
We do have a HARMONIE scripting system which also permits the running of other LAM model configurations which are contained in the shared ALADIN-HIRLAM NWP system, such as ALARO and ALADIN (but which are not developed or supported by the HIRLAM community). When people use the scripting system in this way in presentations and/or publications, we urge them to be careful to specify which model configuration they are actually running and NOT just call it "the HARMONIE model / system".
