Abstract

It was recently shown (Masciadri et al. 2000, Masciadri 2001a), using a numerical simulation (Meso-Nh model), that the hypothesis of considering horizontally uniform C N can have severe consequences. For example, the integration of the C N along lines of sight different from the zenith gives variations that can be larger than 0.50 . In this paper we try to validate this result following two approaches. (a) numerical approach: we compare measured and simulated C N profiles. The first ones were obtained with a Generalized Scidar (GS) and the latter are simulated with the Meso-Nh model at the same azimuth and elevation as those of the observations. Further measurements (DIMM, mast and balloons) are considered in order to support the comparison. (b) experimental approach: we compare C N profiles measured (almost simultaneously) by a GS along different lines of sight. The results of this study show that (1) the horizontal size of the turbulent layers can be finite, (2) the simulations an...
