This is a single sensor, multiple swath SSTskin product for a single day-time period, derived using observations from the AVHRR instrument on the NOAA-XX satellites. It is provided as a 0.02deg x 0.02deg cylindrical equidistant projected map over the Southern Ocean region 3°E to 158°W, 27°S to 78°S. Only day time passes are included in the product. Each grid cell contains the 1 day average of all the highest available quality SSTs that overlap with that cell, weighted by the area of overlap. The diagram at https://help.aodn.org.au/satellite-data-product-information/ indicates where this product fits within the GHRSST suite of NOAA/AVHRR products. Matchups with buoy SST observations (adjusted to skin depths) indicate typical 2014 biases of < 0.1 degC and standard deviations of 0.5 degC to 0.6 degC for NOAA-18 and NOAA-19.
