Metocean data for Wind Parks

HERMESS services are based on a number of (open source) models, for example to provide weather forecasts, tidal currents, and shallow water bathymetry. Furthermore, we have different databases on wind and wave statistics. To drive these regional/local models we use data from large scale models, (real-time) in-situ data and earth observation data.

HERMESS is currently investigating how to improve wind hindcast and forecast by assimilating Earth Observation (EO) data in its weather forecast model. EO data are the only affordable data source to obtain upwind wind data information in offshore areas and to provide sufficient detail over complex land terrain. Candidate EO data are Global Navigation Satellite System (GNSS) delay data, sea surface wind from scatterometers and Atmospheric Moving Vectors (AMV) from meteorological satellites (e.g. MSG-SEVIRI).

HERMESS has recently joined the ISSWIND consortium bidding for the associated European Space Agency (ESA) project, which aims at improving wind information for wind parks. Based on business analysis the definition of ISSWIND integrated solution comprises the following groups of services, all sustained by a strong business case:

  • ISSWIND Service 1: Wind resource maps
  • ISSWIND Service 2: Wind and wave hindcast databases
  • ISSWIND Service 3: Weather forecasts
  • ISSWIND Service 4: Wind power forecasts

The new service will provide better wind data for wind parks in near-shore areas or complex hilly / mountainous terrains.

Example: Windpark Noordoostpolder windfarm in the Netherlands.
