	abstract = {<p>The time series of satellite infrared AVHRR data from 1985 to 2005 has  been used to produce a daily series of optimally interpolated SST maps  over the regular grid of the operational MFSTEP OGCM model of the  Mediterranean basin. A complete validation of this OISST (Optimally  Interpolated Sea Surface Temperature) product with in situ measurements  has been performed in order to exclude any possibility of spurious  trends due to instrumental calibration errors/shifts or algorithms  malfunctioning related to local geophysical factors. The validation  showed that satellite OISST is able to reproduce in situ measurements  with a mean bias of less than 0.1K and RMSE of about 0.5K and that  errors do not drift with time or with the percent interpolation error.</p>},
