WRF Model Methodology for Offshore Wind Energy Applications

Table 3

Statistical metrics (MAE in m/s, ME in m/s, STD of the ME in m/s, and 𝑅) for wind speed at 8 vertical levels (30–100 m), so as to evaluate the performance of different input datasets (NCEP versus ERA-Interim) at the 3 km WRF modelling domain.
