inversion methods

evaluate SAA tolerances to inversion methods (iterative minimization schemes, direct matrix inversion, etc.)

level-2 inversion vs level-3 inversion

Evaluate impact of model inversion applied to satellite Level-3 mean Rrs rather than Level-2 Rrs retrievals.

sensitivities

evaluate SAA tolerances to noisy Rrs, the T/S dependence of aw and bbw, etc.

validation (via NOMAD and SeaWiFS match-ups)

SAA performance for in situ and satellite Rrs compared to in situ IOPs

global algorithm comparisons

coverage comparisons
