| Abstract |
In the present work, we assess the performance of generic products of sea level anomaly (SLA) in manifesting mesoscale eddies of the Western Mediterranean. As 'ground truth' in this study we use eddy manifestations found in sea surface temperature (SST) fields of the region of interest. Co-location of eddies found in thermal imagery with closed contours of the fields of SLA showed that only anticyclonic eddies exceeding approx. 70 km in diameter can be more or less sustainably manifested in the fields of SLA and its derivatives. Detection of cyclonic eddies, presumably due to their small spatial and temporal scales and non-geostrophic nature, is problematic. A preliminary analysis of the along-track SLA data seemed to support the conclusions made for the gridded SLA products. |
