2.2 If not, where do you require additional gauges?
2.3 Do you require data from beyond your national boundaries?
2.4 If yes, then from which countries?
2.5 Does your agency have any real time operational data transfer
links with other agencies?
2.6 If yes, then with whom?
2.7 Are there any other sea level agencies in your country?
Gauge specific questions
==================
Please answer questions 3 to 7 for each gauge in your national network. (You
may have to make several copies of these questions)
3. Gauge Information:
---------------------
3.1 Gauge name:
3.2 Latitude:
3.3 Longitude:
3.4 What is the first year of recording?
3.5 Is data available in digital form? (yes/no)
3.6 How long is the digitised record
3.7 What is the sampling rate at this gauge?
e.g. 10 minutes/hour, continuous averaging over 15 minutes,
hourly means etc
3.8 Monthly/annual means supplied to PSMSL? (yes/no)
3.9 Gauge committed to GLOSS (yes/no)
3.10 Gauge used in a storm surge warning system, or is data
used in storm surge modelling?
3.11 Is real time data supply possible? If not, what is the delay
before data is available?
4. Additional parameters measured at this site:
-----------------------------------------------
4.1 Wind speed (yes/no)
4.2 Wind direction (yes/no)
4.3 Air temperature (yes/no)
4.4 Air pressure (yes/no)
4.5 Salinity (yes/no)
4.6 Sea temperature (yes/no)
4.7 Other parameters:
5. Gauge description:
---------------------
5.1 What type of gauge is it?
e.g. acoustic, float, bubbler, pressure transducer, radar
5.2 Gauge manufacturer
5.3 How often is gauge serviced?
5.4 Is the gauge serviced by your agency, or an outside contractor?
6. Levelling and geodetic information:
--------------------------------------
6.1 How often is the gauge levelled to local benchmarks?
6.2 What is the level of tide gauge zero (TGZ) relative to EUVN?
6.3 What is the level of TGZ relative to the national
levelling network?
6.4 Description of tide gauge benchmark (TGBM)
6.5 Benchmark levels relative to TGZ and national levelling network
6.6 Auxiliary benchmark description
6.7 Is there permanent CGPS at this gauge (within 1 km)?
6.8 What is the GPS' four letter EUREF code (if applicable)?
6.9 If no permanent GPS, has the gauge been fixed as part of any GPS
campaign (e.g. EUROGAUGE)?
6.10 What is the underlying geological characteristic?
(rock/sediment/rubble infill)
6.11 Is the gauge signal likely to be influenced by river outflow,
density changes etc (particularly if gauge is on an estuary)?
7. Any other information:
