Next I plan to implement the Mitrovica formulas (@ Geophys. J. Int. (2011) 187, 729–742) or something that does the same work.
The importance of this has grown on me since the advent of bogus scientific papers have been showing up in the journal Nature (Questionable "Scientific" Papers, 2).
We need multiple ways to calculate ice volume loss from Greenland, Antarctica, and the smaller glacial areas like Glacier Bay.
The two papers I recently criticized attack the settled science concerning CO2 quantity growth in the atmosphere (Mauna Loa), and ice sheet mass loss at Antarctica and Greenland.
The fingerprint technique is another way to realize that ice mass is being lost at Greenland and at Antarctica (e.g. T(θ, ψ, t) = −SL(θ, ψ, t) @Mitrovica).
The sloppy scientists doing those questionable scientific papers are most likely not aware of the fingerprinting technique.
That technique will confirm the continued ice sheet mass loss at those locations combined with using time-warn tide gage records at reliable PSMSL stations (and also bust them, so we will "Book 'em Danno").
The "distances" database, which I have now completed, will help determine where sea level rise (SLR) or sea level fall (SLF) is being caused by loss of ice sheet mass.
We have to keep a step ahead of the growing number of hopium-filled or deceit-filled people who care too little for accuracy.
Anyway, I now have the table built which contains the distance from each PSMSL station to Greenland, Antarctica, and Glacier Bay.
Those distances can be used to help fingerprint where SLR or SLF at each station is coming from:
"Estimating mean global SL alone ignores the information content inherent to geographic variability. As an example, it is now well understood that the rapid melting of any individual grounded ice reservoir gives rise to a distinct and highly nonuniform pattern—or fingerprint—of static equilibrium sea level change. In particular, in the near field of a melting ice sheet (within ∼2,000 km of the margin), SL will fall due to both crustal uplift and the reduction of the gravitational pull on the ocean from the ice sheet. This fall can be an order of magnitude greater than the equivalent rise in mean global SL associated with the meltwater addition to the ocean. In contrast, in the far field of the ice sheet, SL will rise with (generally) greater amplitude as the distance from the ice sheet increases; this rise can exceed the global mean value by ∼30%. These fingerprints provide a framework for moving beyond inferences of globally averaged SL rise to estimate the contributions from individual meltwater sources."(PNAS, emphasis added). Distance is one important factor, so, the "distances" table now added to the mix may help us all in our calculations from now on.
I am beginning to see more of the value in having one more tool in the toolbox.
