Conclusion and perspectives

Different types of downscaling chain to face different types of demands and studies

Implemented on 2 different types of computer ( PC cluster and the NEC) to deal with the computing time constrains.

Armillaire - the multi-support multi-mission GUI - to manage both the hardware and software part

Axes of improvement : CANOPY : 1D surface boundary layer, included in surfex (surface

Model) Optimise Arome on a PC cluster or (big) PC computer Develop an externalised system based on Arome on a perfomant PC

running outside of Météo-France
