Validation of High Resolution SST against in situ included

FRAC data were regrouped under High Resolution data and provision made for MODIS & VIIRS SSTs

L4-SQUAM intercomparison community paper submiited in DSR-II, Special issue for climate studies

OSTIA reanalysis (1985-2007) included L4-SQUAM (ice mask not analyzed)

Ice-masks were applied in L4-SQUAM when ice bit-mask is available; analyses performed in two ways: ice included, ice excluded
