All ENFOR forecasting products share the same underlying engine required by an online system. This engine is a time controlled system with automatic retries which controls the internal and external data flows in online operation. Furthermore, this engine contains routines for data import/export, checking, resampling, etc.
Generally, forecasts are supplied together with standard uncertainty intervals. For cases where the meteorological forecast uncertainty are significant the standard forecasts can be supplemented with quantile forecasts, which are highly reliable representations of the uncertainty.
In order to include the development over time in the representation of uncertainty reliable scenarios can further supplement the standard forecasts. These scenarios can furthermore be generated jointly across the forecast products. In this way all relevant auto- and cross-correlations can be accounted for.
