The data collected during LIWEX and ERS-SYMPLEX cruises have been used to verify the performance of ERS-1/2 and TOPEX/POSEIDON altimeters in the Mediterranean sea. Measurements taken during LIWEX experiment in the Levantine basin (spring 1995) firstly suggested the strong correlation between dynamic heights and sea level anomalies (SLA) in the Mediterranean sea. The ERS-SYMPLEX experiment has been carried out in the channel of Sicily during spring 1996 in order to make a direct comparison between SLA from ERS1/2 and TOPEX/POSEIDON altimeters and in situ data. During the cruise CTD and XBT casts have been done in the central and eastern regions of the channel, and particularly densely along selected altimeters' tracks at the same time of the satellite pass. Sea level anomalies have been computed and compared with the dynamic heights and with the main circulation features resulting from SYMPLEX cruise. The results definitively prove the capability of the two altimeters to correctly detect both basin and mesoscale features of the mediterranean circulation. Collinear analysis along a repeated T/P track has also suggested potential use of SLA in order to detect barotropic component of currents in the channel of Sicily.
