Time reference in MOHID tide

Postby vborges@eptisa.com » Fri Feb 12, 2010 16:25

Hi,
When I use the MOHID Tide I get the phase and amplitude for the constituents in my area. There is also a time ref (in the output dat file) which by default is set to zero. Exactly where is this zero time? 1st of january of year 0001?
Thanks
Vasco

Hi Vasco,

This is the reference time relatively to UTC. For example for Portugal is zero. Spain, +1.

Hope this helps,
Luis

Thanks Luis,

Here's another question, I just extracted the tide constituents for my place of interest, I add them together and I have my tide curve but I don't know where my tides starts, or which tide will I have for tomorrow at a precise time.

I realize that mohid will do this for me but if I want to work out the numbers by myself, how can I reference my tide curve with time?

Cheers,
Vasco

Hi Vasco,

If I understood correctly you want to reconstruct the tidal elevations from the harmonic constituents, is that it?
You can use the TidePreview program in the mohid.com website download area.

Hope this helps,
Luis

Hi Utong,

What exactly is the run-tide.bat program?

Do you mean when you generate the tide file? For the tide file, in each gauge just edit the keyword

TIME_REF : 7.

And in the Model_x.dat input data file edit the keyword

GMTREFERENCE : 7

Hope this helps,
Luis
