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

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.

RMN - Rete Mareografica Nazionale，即意大利国家潮位测量网，由意大利国家环境保护与研究中心（ISPRA）下属的国家海洋测量服务（Servizio Mareografico Nazionale）负责管理。该网络替代了先前由公共工程部运营的海洋水位监测网络。对于所有站点，均采用毫米级精度的微波水位传感器（雷达）监测水文水位。每个水位传感器通过连接至最近的IGM地标进行校准。所有站点均配备了风速风向传感器（10米高度的风速和风向）、气压传感器、空气温度传感器、水温传感器以及相对湿度传感器。此外，10个站点配备了多参数探头，用于水质评估。测量参数包括水温、pH值、电导率和氧化还原电位。所有站点均配备了本地数据管理和存储系统，以及实时向罗马SMN中央办公室传输数据的传输设备（UMTS）。另外，9个用于特定现象（异常波浪）测量的战略站点配备了第二套数据传输系统，通过搭载IRIDIUM技术的卫星进行传输，即使在UMTS系统断电的情况下也能确保连接。
