An experimental global, 3-hourly, 1/4° resolution, skin SST analysis (“GAMSSA_skin”) have been developed at the Bureau of Meteorology as part of the BLUElink-II Project. The skin analysis is formed by adding a simple, empirically based estimate of DSST at that time to the daily RAMSSA SSTfnd or GAMSSA SSTfnd analysis. That is, RAMSSA_skin SSTskin = RAMSSA SSTfnd + DSST – 0.2°C and GAMSSA_skin SSTskin = GAMSSA SSTfnd + DSST – 0.2°C, where DSST = SSTsubskin – SSTfnd, calculated from a simple algorithm developed by Chelle Gentemann, based on geostationary SEVIRI SSTsubskin and AMSR-E surface wind data (Gentemann et al., 2003). The maximum range of the DSST model is 0 to 3°C. A constant 0.2°C is used to transform the SSTsubskin estimate to SSTskin following the SEVIRI skin to subskin constant 0.2°C adjustment (OSI-SAF Project Team, 2006). For GAMSSA_skin, the mean 3-hourly, 1.25º lon x 0.833º lat resolution, 10 m winds from the Bureau’s pre-operational, ACCESS-G global NWP 24 hour forecasts are used.
