The recently proposed PRFG3 method is extended in order to synthesise an atmospheric boundary layer flow, which can be used as inflow condition for Large Eddy Simulation (LES). Firstly, PRFG3 is used for generating homogeneous isotropic and homogeneous anisotropic turbulence fields. Based on the obtained results, the method is applied to generate an atmospheric boundary layer, which is used as inflow condition for a LES of a uniform rough terrain, specified in agreement with the Eurocode. Results are discussed based on the analysis of one and two points statistics of the flow field. Good agreement between the target values used in the inflow generation, the synthetic field and the LES, highlights the soundness of the proposed approach.

Abstract
The recently proposed PRFG3 method is extended in order to synthesise an atmospheric boundary layer flow, which can be used as inflow condition for Large Eddy Simulation (LES). Firstly, PRFG3 is used for generating homogeneous isotropic and homogeneous anisotropic turbulence fields. Based on the obtained results, the method is applied to generate an atmospheric boundary layer, which is used as inflow condition for a LES of a uniform rough terrain, specified in agreement with the Eurocode. Results are discussed based on the analysis of one and two points statistics of the flow field. Good agreement between the target values used in the inflow generation, the synthetic field and the LES, highlights the soundness of the proposed approach.
