Main goal

I’m interested in evaluating the radiative impact of aerosol dust on atmospheric dynamics which is an important component of the climate system but is still poorly quantified. To reach my goals, I use an observations-modelling coupled aproach. In term of modelling my mean is the regional atmospheric model MesoNH coupled […]
