Marine Data

  • The Irish Marine Buoy Network is a collaborative project involving the Marine Institute, the Department of the Marine and Natural Resources, Met Éireann and the UK Met Office.
  • The Network comprises of six moored buoys around the Irish coast. Each buoy is approximately 6m high, and carries a dual set of sensors which measure wind speed and direction, air temperature, atmospheric pressure, sea surface temperature, wave height and wave period. The data are sent hourly from the buoys to a ground station in Darmstadt, Germany, from where they are routed to Met Éireann HQ in Dublin.
  • It takes between 4 to 6 weeks to quality control the data and input to our climate data base.
  • The first buoy, M1, has been reporting hourly since the 6th November 2000.

Irish Marine Data Buoy Network

    Weather reports are available from ships located within 200km of the Irish Coast. [48° to 59°and 3°to 16°W] for the period 1854 to 1995. Parameters available: Wind speed and direction, air temperature (dry bulb and wet bulb), sea temperature, sea height, swell height, swell period, swell direction, cloud amount, cloud height, visibility. Products available: individual ship reports, frequency tables of any rectangular area for any time period of wind speed versus direction, wave height versus wave period, wave height versus wave period in any direction segment
  • Historical Data:
    Some manual Lighthouse (several years of data between 1985 and 1997) and automated Light Vessel Reports (short periods between 1939 and 1973) are also stored. Some of this data is stored on paper only.
