Abstract
Many instruments are able to provide local (in space and time) estimations of all the astroclimatic parameters that depend on the optical turbulence. The numerical technique is, at the present time, the only approach that can provide 3D characterization of the optical turbulence. Since a few years, many efforts have been dedicated to increase the reliability of the atmospherical meso-scale model called Meso-Nh in simulating C[N]2 profiles above astronomical sites. The most recent and promising results have been obtained above the San Pedro Mártir site. In this paper these results are summarized.
