An experimental, regional, hourly, 1/12° resolution, skin SST analysis (“RAMSSA_skin” ) has been developed at the Bureau of Meteorology as part of the BLUElink-II Project. The skin analysis are formed by adding a simple, empirically based estimate of DSST at that time to the daily RAMSSA SSTfnd. That is, RAMSSA_skin SSTskin = RAMSSA 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 RAMSSA_skin, the inputs to the DSST algorithm are mean hourly, 0.375º resolution, 10 m winds from the Bureau’s pre-operational, ACCESS-R regional NWP 24 hour forecasts.
