A spectral analysis from wind tunnel and near-neutral atmosphere data was realized. The measurement spectra are compared with von Kármán and Kaimal expressions and a complementary evaluation based on the previous work of Arbage and Degrazia et al. was realized. A comparison of the vertical component with atmospheric values is also considered and the atmospheric stability effects on full-scale measurements are also analyzed. Parameters used to obtain dimensionless spectra including mean velocity, the variance of velocity fluctuations, the longitudinal integral length, local friction velocity and the mean turbulent kinetic energy dissipation.
