Short summary
In this paper, quasi-empirical convective eddy diffusivity parameterizations for a coastal site are obtained. In the derivation we used Taylor's theory of statistical diffusion and sonic anemometer observations collected at 11 levels on a 140 m high tower in a convective planetary boundary layer. The test of the derived coefficients was solved by solving the equation of diffusion–advection by the fractional step/locally one-dimensional (LOD) methods.
