The telemetric stations transmit their data, acquired every 10 minutes, to the HYDRONET server at NOA’s Institute for Environmental Research and Sustainable Development (IERSD/NOA). These data are automatically forwarded to and entered in the OpenHi.net platform operated by the Institute of Communication and Computer Systems (ICCS/NTUA). The data are freely available to any interested party.
Software has been developed by the HYDRONET team for the automatic quality control of data. The database of HYDRONET receives the current measurements from the stations, but includes also hydro-meteorological data series recorded during the program DEUCALION (2011-2014).
Streamflow campaigns: The HYDRONET team performs systematically streamflow campaigns at each station for the development of rating curves. In these hydrometric campaigns, observations are made either in-stream, with a current meter, and/or from outside of the stream, with a hand-held radar measuring the surface velocity. In addition, cameras installed at the monitoring stations record visually the stream status at 10-min intervals.
