Short summary
This study presents a methodology to investigate the ability of satellite altimetry to observe a coastal current, the Northern Current, in the NW Mediterannean Sea. We use a high-resolution regional model, validated with HF radars and in situ data. The model is used as a reference and compared to three different missions (Jason 2, SARAL and Sentinel-3), studying both the surface velocity and the sea surface height signature of the current. The performance of the three missions was also compared.
