Le GMAP est un groupe de recherche du CNRM (Centre National de Recherches Météorologiques) affilié à Météo-France et au CNRS (Centre National de la Recherche Scientifique).

GMAP is a research group of CNRM (National Centre of Meteorological Research) affiliated to Météo-France and to CNRS (National Centre of Scientific Research).

Our activities

The AROME model was declared operational on 18th Dec 2008.

The GMAP group develops numerical weather prediction (NWP) software for Météo-France. The main activity is on three NWP systems:

• ARPEGE, a global model of the atmosphere with a 4D-Var data assimilation scheme
• ALADIN, a regional high resolution model of the atmosphere with a 3D-Var data assimilation scheme.
• AROME, a convective scale fine resolution model of the atmosphere with a 3D-Var data assimilation scheme.

Besides this research and development for NWP activities, GMAP pursues some more fundamental scientific research: on the dynamics of midlatitude storms, on atmospheric predictability, on the use of satellite data, on data assimilation techniques, on mathematical techniques for numerical modelling of the atmosphere, etc... For more information on these topics, please follow the Science themes links below. These activities are embedded in many cooperations and collaborative .

Team structure

Links to our main partners

• Météo-France and CNRS are our host institutes.
• We participate in Numerical Weather Prediction R&D activities of two consortia of many AfroEuropean countries: ALADIN and HIRLAM, under a strong partnership with the ECMWF European Weather Centre.
• Our European cooperation activites take place under the umbrella of the SRNWP pan-European coordination and the World Meteorological Organization.
• The AROME physical parametrization were developed in partnership with the Méso-NH modelling group
• The RECYF team played a leading role in the FASTEX international field experiment.
• Satellite data assimilation activities are undertaken in cooperation with the NWP SAF group under the auspices of the Eumetsat space agency.
• We have links with OHM-CV on several research programmes such as the planned Hymex field experiment and Mediterranean flood forecasting.
