Such ‘retrieval-space’ dependent biases are difficult to uncover using customary validation (will take a long time) (as to why customary validation is inadequate!)
The SQUAM diagnostics helped uncover a bug in the MUT SST which was causing across-swath bias >0.7K.
After correction, bias reduced to ~0.2K and symmetric with respect to nadir.

Roughly, L4 products form 3 major groups(when compared against GMPE):
Planned community publications in Deep-Sea Res-II, Special Issue (proposed abstracts accepted; manuscripts are due in June 2011):
1. Group for High Resolution SST (GHRSST) Analysis Fields Inter-Comparisons: Part 1. A Multi-Product Ensemble of Sea Surface Temperature Analyses
