What these results do—and do not—show
These saved results describe the Portugal base model only. They do not establish accuracy for other countries, current cloud upgrades, or every forecast horizon. The saved report does not specify the evaluation dates or horizon breakdown.
Individual forecasts can have larger errors. These figures are not an overall SAO accuracy percentage or a guarantee of flight conditions.
