The meteorological stations of the network can be composed of sensors that measure precipitation (rain and/or snow), the physical characteristics of the air (temperature, humidity) and other atmospheric phenomena (pressure, direction and speed of the air, solar radiation) The first organic national hydrometeorological survey network was established in the first decade of the 1900s with the creation of the Hydrographic Office of the Water Magistrate. This office managed it for almost 100 years and expanded with a substantial number of measuring stations. In 2001, the state administration transferred hydrological monitoring responsibilities to the Regions and in 2002 it also transferred the monitoring stations observed until then. The current hydrometeorological survey network managed by the Friuli Venezia Giulia Region consists of 190 active stations, mono or multiparametric, both with automatic detection with remote data transmission, and with manual detection or local recording. The teletransmission network is totally shared with the regional Civil Protection.
