Abstract : A model for turbulence in the marine atmospheric surface layer has been developed and evaluated. The model uses only standard meteorological parameters and is suited to become part of a technical decision aid to predict optical turbulence and refractivity effects. In addition, the model provides all the basic tools to calculate the vertical profiles of wind speed, air temperature and air humidity, the micrometeorological parameters such as stability, roughness lengths, exchange coefficients and the fluxes of momentum, heat, water vapor. These results are used to estimate the structure function parameters for the refractive index, C(2)(sub n), which is the controlling parameter for the prediction of scintillation, blurring and beam wander.
