[MITgcm-devel] ice/snow pdf

[Fenty, Ian G (329E)]

Martin,
Everyone knows that 0.99999 ...  = 1,  so I'm ok if you toss those old verifications!

It would be great to have capability to prescribe arbitrary ice thickness distributions.
My vote is to include.

Unfortunately, results change from 16 to 14-11 digits of aggreement for basically all experiments that use SEAICE_multDim=7. The reason is, that Fortran doesn't know that 7/7=1, but 0.9999999999978 or so. Do we care? Or do we care enough about prescribing an observed ice thickness distribution that we don't care about these small difference? If not, I'll just scrap this effort.
