Paper Abstract

The refractive index gradient, averaged over short horizontal paths, in the atmosphere was experimentally investigated by using a method we developed, based on the use of thin parallel laser beams. Horizontal and vertical components of the gradient were shown to be directly related to the corresponding lateral displacements of the beams at the end of the path. The method is here described and results of measurements made in different locations and conditions are presented. Some cases of strong anisotropy were also found, which can be related to the local air convective movements from the ground.
