Influence de la couche atmospherique marine sur la propagation electromagnetique
conference paper
The assessment of refractive effects requires a detailed knowledge of the vertical profiles of temperature, humidity and pressure, generally supplied by micro-meteorological (bulk) models. Such models only apply to the surface layer, and do not take into account the particularities of the lower marine atmosphere, such as the presence of waves and aerosols. A sensitivity study with the Dutch ray-tracer ARTEAM has shown that a proper prediction of refractive effects relies heavily on a detailed characterization of the wave surface, whereas a bias in meteorological observations is relatively acceptable. A comparison of various models to generate the required input profiles for the raytracer has indicated the benefits of including turbulence and boundary layer effects in these models.
