MESO-NH

 

What is Meso-NH?

Meso-NH is the non-hydrostatic mesoscale atmospheric model for the French scientific community, jointly developed by LA (Laboratoire d’Aérologie) and CNRM-GAME (a CNRS/Météo-France joint research unit).

Meso-NH:

  • Uses a non-hydrostatic system of equations to handle the whole range of scales – from synoptic to large eddy – when calculating budgets;
  • Offers a wide range of physical parameterizations, including advanced ones for the representation of clouds and precipitations;
  • Is coupled with the SURFEX land surface model, in order to represent interactions between the atmosphere and different types of surface (vegetation, city, ocean, lake);
  • Allows for a multiscale approach through a nested-grid technique;
  • Is a versatile, vectorized, parallelized code, operating in 1D, 2D and 3D, designed to handle both real situations and academic cases;
  • Is coupled with modules for chemistry (including gaseous, aerosol and aqueous phase) and for lightning;
  • Uses observation operators directly comparing model output with satellite, radar, lidar and GPS observations.

Starting from version 5.1, Méso-NH is freely available via CeCILL-C licence contract.
