AbstractIn this article, is proposed to identify the methods for estimating aerodynamic roughness length (z0) best suited to feasibility studies for the construction of wind farms. For that, a systematic review is carried out to filter the latest works that apply different methods to find z0 values. Identifying z0 for a specific surface is important to simulate the vertical wind profile and mechanical and turbulent fluxes estimation in the atmospheric surface layer. Must be considered those factors in viability studies for a wind farm, therefore impacting the calculation of energy efficiency. Morphometric and micrometeorological methods are listed, besides presenting works that have developed tables with z0 optimal values for different types of land. In the end, situations are presented in which each method has better applicability.
