Atmospheric boundary layers for open, suburban, and urban terrain were simulated in the Iowa State University Aerodynamic-Atmospheric Boundary Layer (AABL) Wind and Gust Tunnel using stationary turbulence generating obstacles. The individual and combined effects of the obstacles were analyzed in order to simplify the simulation of additional boundary layers in the future.;The mechanical bypass duct gusting system of the AABL facility was used to generate various gusts within smooth and turbulent flows. An exploration of the gust-generating system led to the selection of types of gusts that were studied further. Analysis of the gust velocity data using wavelet theory demonstrated that the gust events had no measureable effect on the turbulence intensity or Reynold's stresses within the atmospheric boundary layers.
