Dataset of the National Tide Gauge Network of RMN – Rete Mareografica Nazionale, Italy (since 1973)

Data holding centreISPRA-Institute for Environmental Protection and Research
CountryItaly  Italy
Time periodFrom 1973 (ongoing)
Geographical area

The National Tidegauge Network is composed of 33 measuring stations uniformly distributed throughout the national territory and mainly located within the port facilities.


Alkalinity, acidity and pH of the water column; Sea level; Air pressure; Air temperature; Atmospheric humidity; Electrical conductivity of the water column; Wind strength and direction; Water body redox potential


Meteorological packages; sea level recorders; water temperature sensor


RMN - Rete Mareografica Nazionale - The Italian National Tide Gauge Network is managed by the National Maritime Service (Servizio Mareografico Nazionale) of the Institute for Environmental Protection and Research (ISPRA). It replaces the pre-existing sea-level monitoring network operated by the Ministry of Public Works. For all the stations, the hydrometric level is monitored with a new microwave level sensor (radar) with millimetre accuracy. Each level sensor is referenced by connecting to the nearest landmark IGM. All stations are equipped with a wind sensor (speed and direction of the wind at 10 metres), with a barometric sensor, an air temperature sensor, and a water temperature sensor, in addition to a relative humidity sensor. Furthermore, 10 stations are equipped with a multiparameter probe for the assessment of water quality. The measured parameters are: water temperature, pH, conductivity and redox. All stations are equipped with a local system for managing and storing data and a transmission device (UMTS) in real time to the central office of the SMN in Rome. In addition, 9 strategic stations for the measurement of particular phenomena (anomalous waves) are equipped with a second data transmission system, via satellite with IRIDIUM technology, ensuring connection even in the event of a black-out of the UMTS system.
