The goal is to describe the spatial structure of stationary homogeneous turbulence under a neutral atmospheric stratification using only 3 adjustable parameters.\n\n## Content\n\nThe present submission contains:\n- The function MannTurb.m that computes the sheared spectral tensor\n- The function MannCoherence that computes the wind co-coherence\n- A LiveScript for the example file\n- A data file GreatBeltSpectra.mat that contains the wind spectra from the Great belt bridge experiment for comparison with the computed spectra.\n\nAny question, comment or suggestion is warmly welcomed.\n\n## References\n\n[1] Mann, J.
