IMOS - Satellite Remote Sensing - SST - L3S - Single Sensor - 3 day - day and night time - Australia

This is a single-sensor multi-satellite SSTfnd product for a 72 hour period, 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 72 hour 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. The SSTfnd is derived by adding a constant 0.17 degC to the SSTskin observations after rejecting observations with low surface wind speeds (&lt;6m/s by day and &lt;2m/s at night) (see http://www.bom.gov.au/amoj/docs/2011/beggs.pdf). Matchups with buoy SSTfnd observations for the central date indicate typical 2014 biases of &lt; 0.05 degC and standard deviations of 0.6 degC.  Refer to the IMOS SST products web page at http://imos.org.au/sstproducts.html and Beggs et al. (2013) at http://imos.org.au/sstdata_references.html for further information.
Production of this single sensor product ceased in June 2025, due to decommissioning of the NOAA-18 satellite.
