4 years ago Thoughts: M2, 10 days, harmonic analysis
as a very quick test perhaps go with sf_L51_r24, sf_L51_r10 (so we have an idea of the impact of rmax)
then in addition: sz_L51_r10_s26 (being quite ZPS-like) and MEs_L51_r10-07
Sound ok?

4 years ago Ran basic comparisons against SF12 51 constituents included: clname(1)='M2' clname(2)='S2' clname(3)='O1' clname(4)='K1'
started run 10-12-2013 ran out until March 2014. Assessed only the ssh data for JAN-FEB.
Experiments included:
Quoting Enda: The change in the definition of the bottom may have a substantial effect on the tides, And might be one of the places that the difference between z-s and Diego’s ME s is significant.
That might be one of the slowest parts of getting this domain right. A simple run with tides and a straight up diff of SSH amp over a day once its spun up might be sufficient in the first instance to observe differences in the model solutions. Could even just be constant density ocean without any forcing, just the tides.
A short run with say just M2 say 10 days, and switching on the harmonic analysis to dump out a M2 Amp/phase and then comparing the various set ups for the short run just in terms of sensitivity never mind accuracy in the first instant.
If they are not very different at that point can think about longer runs with multiple constituents And comparing against obs but I have a feeling the difference could be significant so that simple field difference of just M2 for a short run might be a good starting point and a cheap experiment.
