Three tide gauge stations have been installed in June 2013 in Koroni, Kihtira, Paleochora and are operated in cooperation with JRC. Data from those stations are available to NOA-HLNTWC and JRC in real time. Each station is consists of two sensors, one pressure and one microwave sensor (radar) and a CGPS.
Four tide gauge stations, with microwave sensors, have been installed, in 2013, in Santorini and Corfu Islands and in 2014 in Rhodes Island and Thessaloniki, with data transmitted to NOA-HLNTWC in real time.
Networks operated by NOA
Five out of 21 tide gauge stations of the Hellenic Navy Hydrographic Service are already available in real time to NOA-HLNTWC via ftp communication procedure.

In the framework of cooperation with JRC, both MOD1 & 2 scenario databases have been fully installed and are already in use. The set of scenarios enables NOA-HLNTWC to estimate wave arrival times and wave heights near the coast. The processing and analysis of the scenarios has been implemented using the Tsunami Analysis Tool.
Tsunami Analysis
![Page 13: National Observatory of Athens - Europa - … · IOC coordinated Exercises ICG/NEAMTWS TSUNAMI EXERCISE NEAMWave14) (b) (c) NOA-HLNTWC alos successfully participated in the NEAMWAVE14](https://reader036.vdocuments.site/reader036/viewer/2022071002/5fbfa4fdbbb7a449dc3138d0/html5/thumbnails/13.jpg)
Moreover, Tsunami Travel Times software (TTT) by Geoware (kindly provided by NOAA) has also been locally installed and the operator has the possibility to estimate the tsunami arrival time either by using the scenario’s travel time or those calculated by TTT

A scripting module has been developed in house following Tsunami Analysis Tool messaging output. This module gives to the user the opportunity to send simultaneously all three types of messages, i.e. e-mail, fax and GTS, the last through the Hellenic National Meteorological Service (HNMS) via the dedicated VPN link between HNMS and NOA HL-NTWC operating centers. The SMS technology has also been used during the last exercise (NEAMWAVE14) and the extended Communication Tests.
Message dissemination
![Page 15: National Observatory of Athens - Europa - … · IOC coordinated Exercises ICG/NEAMTWS TSUNAMI EXERCISE NEAMWave14) (b) (c) NOA-HLNTWC alos successfully participated in the NEAMWAVE14](https://reader036.vdocuments.site/reader036/viewer/2022071002/5fbfa4fdbbb7a449dc3138d0/html5/thumbnails/15.jpg)
Training of the duty officers involved in the 24/7 operation of the HL-NTWC is carried on constantly, since the operators are taking shifts.

NOA-HLNTWC participates in the GTIMS project, coordinated by JRC. The aim of the project is to issue pseudo-messages and create Tsunami Analysis Reports for every potential Tsunami event occurring worldwide caused by earthquakes of magnitude equal or greater than 7.0 for a period of 1 year.
Applied to also participate in the second phase of the project – GTIMS2.
