| Summary: | Credit Australia’s Integrated Marine Observing System (IMOS) is enabled by the National Collaborative Research Infrastructure Strategy (NCRIS). It is operated by a consortium of institutions as an unincorporated joint venture, with the University of Tasmania as Lead Agent. Credit Bureau of Meteorology (BOM) Credit CSIRO Marine and Atmospheric Research (CMAR) This is a single-sensor SSTfnd product for a single 24 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 Southern Ocean region 3°E to 158°W, 27°S to 78°S. Each grid cell contains the 24 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 (<6m/s by day and <2m/s at night) (see http://www.bom.gov.au/amoj/docs/2011/beggs.pdf). Matchups with buoy SSTfnd observations indicate typical 2014 biases of < 0.01 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.
