Tidal parameters #38

Hi,

isn't there any possibility to provide tidal parameters (amplitude factor and phase shift) like in ETERNA's PREDICT for the calculation of synthetic Earth tides?

In PREDICT (also in TSoft, etc.) amplitude factors and phase shifts can be provided for phase groups that are specified by an upper and a lower frequency, e.g.: TIDALPARAM= .000146 .003426 1.000000 .000000 SA #ANALYZE wave group TIDALPARAM= .004709 .010952 1.000000 .000000 SSA #ANALYZE wave group TIDALPARAM= .025811 .031745 1.000000 .000000 MSM #ANALYZE wave group TIDALPARAM= .033406 .044653 1.000000 .000000 MM #ANALYZE wave group TIDALPARAM= .060131 .068640 1.000000 .000000 MSF #ANALYZE wave group TIDALPARAM= .069845 .080798 1.000000 .000000 MF #ANALYZE wave group ...

Such parameters can be estimated from actual observations or modeled.

Is there any other possibility in PyGTide to provide amplitude factors and/or phase shifts, or is there something hardcoded?

Thanks and best regards, Andreas

Any news about this topics? Is it possible to provide an .ini configuration file or any parameters to provide these factors?

It would be great to get some respone from the developers on this topic.

Hi!

I think it is not possible, but I do not know enough about the internals of ETERNA to be sure. I am sorry that I cannot really help you here.

Ok, thanks!
