The National Centre for Meteorological Research (Centre National de Recherches Météorologiques), CNRM-GAME, Meteo-France and CNRS, is offering a one year position to a scientist specialized in numerical weather prediction in general and data assimilation in particular. The goal is to investigate the benefit of data assimilation compared to dynamical adaptation for a limited-area model.
The main tasks will be to prepare and run a configuration of the ALADIN limited-area model with 3D-Var assimilation over a specific region of interest, and compare it to a reference one (without data assimilation) ; and then to analyse the sensitivity of the 3D Var assimilation scheme to the tuning of various observation sets (benefits of particular radiosondes, increase of radiance density, etc.) ; Some diagnostic tools quantifying the impact of observations in an NWP system will be used.
