Modelling and Assimilation Group for Forecasting
Group director : Francois Bouyssel
GMAP is a research group at CNRM (National Centre for Meteorological Research) affiliated with Météo-France and CNRS (National Centre for Scientific Research).
GMAP develops numerical forecasting software packages for Météo-France. Its activity focuses on three major numerical forecasting systems:
- ARPEGE is a global atmospheric model with a 4D-Var data assimilation scheme.
- ALADIN is a high-resolution regional atmospheric model with a 3D-Var data assimilation system.
- AROME is a fine-scale convective model of the atmosphere with a 3D-var data assimilation scheme. AROME has been in operational mode since 18 December 2008.

Since the 1990s, ARPEGE and ALADIN have been used operationally for weather forecasting at Météo France, while AROME has been operational since late 2008.
All three systems are based on software developed jointly with the CEPMMT. ALADIN is the result of collaboration between the consortium partners ALADIN, AROME is the result of collaboration with CNRS laboratories working on the atmospheric model Méso-NH. International collaboration on AROME now includes the two regional numerical prediction consortia. ALADIN and HIRLAM.
The complexity of collaboration around the ARPEGE/ALADIN/AROME models has resulted in a large but scattered body of documentation.
Most of this documentation is currently archived on the site web GMAPDOC.
In addition to its research and development activities in numerical forecasting, GMAP is involved in fundamental research, particularly on the dynamics of mid-level thunderstorms, atmospheric predictability, the use of satellite data, data assimilation techniques, and numerical modelling of the atmosphere.
