Italian National sea wave and sea level measurement networks

The Italian national buoy network (RON – Rete Ondametrica Nazionale) measures sea wind waves. Real time data are available at:

RON includes 15 directional wave buoys and the corresponding land based receiving stations collecting real time series of wave and meteorological parameters every 30 minutes. It provides data needed to define the sea state, such as: significant wave height, peak period, mean period, wave direction, sea surface temperature, wind speed and direction, air temperature, atmospheric pressure, relative humidity. Buoys transmit data to shore stations within 15 nm and a small dataset via Inmarsat-D+. All shore stations are connected to the control centre based in Rome, using 2 Mbps xDSL channels, implementing a virtual private network.


The Italian national tide gauge network (RMN – Rete Mareografica Nazionale) continuously monitors the sea level and a number of related meteorological physical parameters.

Data (real time and time series) are available at:

RMN includes 36 coastal stations. It is the hugest network for sea level measurement in the Mediterranean, collecting real time series of sea level and meteorological parameters every 1 minute. It integrates the National meteorological system. Data gathered are used for determining tides and seiches and can support the identification and characterization of early tidal waves (tsunami) and of storm tides. Some stations also provide data used for the qualitative characterization of environmentally sensitive marine areas.
