An experimental campaign to measure turbulence in the marine boundary layer
Abstract. There is a lack of measurement data on the spatial structure of turbulence at heights greater than 100 m in the marine atmospheric boundary layer (MBL). Consequently, turbulence models like the Mann and Kaimal models, which are referred to in industry standards, have no...

The AWAKEN wind farm benchmark – Part 2: Modeling results
Abstract. Accurately modeling wind farm performance in complex atmospheric flows remains a challenge. This paper presents the modeling results of the American WAKE experimeNt (AWAKEN) wind farm benchmark, a collaborative effort involving 16 research groups from academia and indus...
