IMOS - SRS - SST - L3S - Single Sensor - 3 day - day time - Australia

This is a single-sensor multi-satellite SSTskin product for three consecutive day-time periods, derived using observations from AVHRR instruments on all available NOAA polar-orbiting 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 the 3 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 for the central date (adjusted to skin depths) indicate typical 2014 biases of < 0.2 degC and standard deviations of 0.6 degC.
