Fitting the Uniform Shear Model to real data

The parameters of the Uniform Shear Model [1] are estimated in the least-square sense

Summary

The function "fitMann" is used to estimate the parameters of the uniform shear model [1] in the least-square sense. As an example, the fitting algorithm is applied to the Great Belt dataset used by Mann [1] and the Kaimal spectral model [2,3]. The present Matlab implementation was applied for offshore wind data [4].

Content

The submission contains:

  • the function fitMann.m
  • An interactive example file Example.mlx
  • An example where fitMann is applied on incomplete data.
  • a data file greatbeltData that contains digitalized spectral estimate from the Great belt experiment
  • The function mannTurb.m introduced in [5]

Any comment, suggestion or question is welcomed.
