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 five moored buoys around the Irish coast. Each buoy is approximately 6m high, and carries a dual set of sensors to 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 where they are routed to Met Éireann HQ.
  • It takes between 4 to 6 weeks to quality control the data and to store on our climate data base.
  • The first buoy M1 has been reporting hourly since the 6th November 2000.
Irish Marine Data Bouy Network
    Weather reports are available from ships made 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
  • Numerical Wave Model Products: The operational wave model WAM is run twice daily and the output is stored every 6 hours in the data base. Monthly averages can be obtained for every grid point. Grid points are every 0.25 degrees between 48° and 57° North and 0° and 15° west.
  • 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.
