The {{ obs }} vs {{ mod }} validation was produced on {{ meta.date.date().isoformat() }} at {{ meta.date.time().isoformat(timespec="seconds") }} {% if meta.user != "" %} by {{ meta.user }} {% endif %} using wind-validation version: {{ meta.version }}. This report first gives a validation summary followed by detailed validation for each of the {{ site_results.shape[0] }} points {% if site_results.index.shape[0] != site_results.index.unique().shape[0] %} obtained at {{ site_results.index.unique().shape[0] }} masts{% endif %}.

Summary Table

Table 1: The aggregated results of the {{ obs }} vs {{ mod }} validation for {{ site_results.shape[0] }} points. Observed and Predicted are the mean observed and modelled values, respectively. ME is the mean error, RMSE is the root mean square error, MAE and MAPE are the mean absolute error. The power density values are calculated for standard air density 1.225 kg/m3.
