General Information of the XIOM:
Oceanographic and Meteorological Instrument Network

Made possible through a collaborative agreement by:

- Departament de Política Territorial i Obres Públiques (Department of Territorial Policy and Public Works)
- Ports de la Generalitat (Ports of the Generalitat)
- Universitat Politècnica de Catalunya (Technical University of Catalonia)
- Servei Meteorològic de Catalunya (Meteorological Service of Catalonia)

 Signed on 11 November 1999 to initiate the maintenance and management of the Oceanographic and Meteorological Instrument Network of Catalonia

Currently the network is formed by:
 
Instrument Location Measurement Data
Directional buoy Cap Tortosa swelldirection real-time
Directional buoy Port Ginesta swelldirection real-time
Scalar buoy Blanes Swell scale real-time
Scalar buoy Golf de Roses Swell scale real-time
Oceanographic L'Ampolla ocean levels In past time
Oceanographic St. Carles de la Ràpita ocean levels In past time
Weather station L'Ampolla temperature, atmospheric pressure and wind In past time
Weather station St. Carles de la Ràpita temperature, atmospheric pressure and wind In past time
Weather station La Cava temperature, atmospheric pressure and wind In past time
 
 
Currently the data gathered by buoys are provided in real-time, which measure the following variables:
 
Maximum height:

The highest wave recorded during the time of the measurement.

 
Significant wave height:

It is possible to calculate the average of a third of the highest waves observed and to correlate the observed height to that which is detected visually.

An example of the calculation of the significant wave height:

pieces of data have been registered showing maximum wave heights of 2.8 m, 2.6 m, and 2.6 m, 2.5 m, 2.4 m and 2.2 m. A third of the tallest waves will be the first two numbers and the average is 2.7 metres.
 
 
Peak direction:

Corresponds to the direction of the wave from the point of maximum energy where it originated

 
 
Average wave period:

Time elapsed between two consecutive waves.
