This presentation was done at the NEWA Final Workshop in April 2019. It presents a summary of the research activities related to the development of the NEWA model chain, which has two branches: one dedicated to the production of the wind atlas, based on the WRF model and statistical downscaling with the WAsP methodology, and another one focused on site assessment tools, based on dynamic downscaling with a variety of computational fluid dynamic (CFD) codes, using both Reynolds-Averaged Navier Stokes (URANS) and Large-Eddy Simulation (LES) turbulence modeling. Alongside model development activities a formal verification and validation (V&V) strategy was implemented, following the IEA Task 31 Wakebench framework, to leverage the experimental database of the project. An open-source model chain based on WRF and OpenFOAM has been released as reference for future model development and validation activities in connection to wind assessment best practices and standards.
