I can now see the software is getting to be a useful tool.
If calculates sea level change (SLC) whether that SLC is sea level rise (SLR) or sea level fall (SLF).
And it does it for all of the 1,417 tide gauge stations around the world.
Those tide gauge stations fit within 36 zones, 18 Northern Hemisphere zones and 18 Southern Hemisphere zones.
That is not to say they are evenly dispersed, because while viewing printout analysis of 54,106 rows in the rlrdata table that there are about 5 of the 36 zones that have no tide gauge stations at all (talk about out in the boonies).
Other zones have a few, others have a plethora of them.
Another thing, there is both SLR and SLF in some of the zones.
That inspired me to work on an analysis algorithm that will isolate SLR and SLF areas.
Just to see how that comports with the fingerprint expectations concerning Greenland and Antarctica at this time.
Anyway, we all owe some gratitude to Dr. Mitrovica and Dr. Gomez for their work to enlighten us.
They helped a lot with ways to avoid mystery and counter-intuitive dynamics one encounters in contemplating the part gravity, axial relocation, and the Earth's rotational impact play in this equation.
The most oft quoted phrase in this context, "mean sea level rise," is about as real and useful as "a mean balanced budget" is in Washington, D.C.
In the days ahead the databases kindly provided by PSMSL and clues provided by Mitrovica and Gomez will prove, I think, to be powerful contributions to those who contemplate making better sea level projection software.
Cheers.
