Hindcast Data Products

From all our forecast models hindcast data are available up to 10 years back in time depending on the start of the individual forecast model delivery.

All forecasts start with a short hindcast in order to get the best starting conditions for the forecast, and adding these "analysis" or "nowcast" data produces a very valuable hindcast data base.

The areas covered by the hindcast data are thus the same as for the forecast model data. (Note, however, that some forecast model are proprietary). For a map of forecast model areas and types of data (deliverables) see links in the section to the right.

Examples of available hindcast data are shown below. Please contact us for terms and costs - see link in the section to the right.
