General description :
Optimal Interpolation SST dataset from all infrared L2P processed in near-real-time mode.
Dataset of gap-free daily sea surface temperature maps (L4 products) produced on the Mediterranean Forecasting System OGCM grid at 1/16° spatial resolution. This L4 SST products are assumed to represent night time SST around 00 UTC and are obtained from AVHRR night-time passages (v0) and from all available infrared sensors (v1). Daily Near-Real-Time (NRT) maps are produced weekly and reprocessed in Delayed Time (DT) after 2 weeks to include all relevant measurements in the analysis. A specific Optimal Interpolation (OI) scheme developed within MFSTEP project (www.bo.ingv.it/mfstep/) is used to combine L2 measures of SST from AVHRR sensors, and to fill gaps where no observations are available. As the Mediterranean sea is characterized by the presence of many islands and peninsulas, the scheme drives a 'multi-basin' analysis to avoid data propagation across land from one sub-basin to the other.
