This is a single sensor, single swath SSTskin product for a single overpass, without distinction between day or night. It is 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 region 70°E to 170°W, 20°N to 70°S. Each grid cell contains a single observation from the AVHRR radiometer. 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.
