If another forecast range is checked as the 1-12 hours below, the following settings are hard coded regardless of the extract settings.
•If the forecast type is not set to ‘Adjusted’in the extract settings, the forecast type will be set to ‘Original’
•The ‘Use observed’ setting will be set to false. This to ensure that weather forecasts and not observations are used.
•The ‘Use normal’ setting will also be set to false. This to ensure that not normal weather is used.
The extract settings serves as a template for the forecast series, weather observations and weather forecast restrictions and are applied for the first interval (1-12 hours). The setting ‘Period to ignore’ is automatically increased by 12 hours for each higher interval. This way, we can simulate forecasts made on longer and longer prediction horizons.
