Dataset for a paper titled "Non k-type behaviour of roughness when 1 in-plane wavelength approaches the 2 boundary layer thickness"

This dataset has the velocity profile data as well as the roughness function data from wind tunnel measurements obtained at 2 different streetwise locations with two different scaled rough surfaces. The attached zip file has 2 subfolders that contain the data at 2m downstream and 4m downstream. The measurements were carried out at 10, 15, 20 and 25 m/s for both surfaces. The zip file also contains a .mat file, which has the original scan of the surface. Note that the scan is the inverse of the surface geometry. Therefore, the values need to be multiplied by -1 to get the actual surface geometry. If you are using this dataset, please cite this paper: B. Nugroho, J. P. Monty, I.K.A.P Utama, B.
