  abstract = {{I}n the context of the {ESA} {C}limate {C}hange {I}nitiative project, we are engaged in a regional reprocessing of high-resolution (20 {H}z) altimetry data of the classical missions in a number of the world's coastal zones. {I}t is done using the {ALES} ({A}daptive {L}eading {E}dge {S}ubwave-form) retracker combined with the {X}-{TRACK} system dedicated to improve geophysical corrections at the coast. {U}sing the {J}ason-1 and {J}ason-2 satellite data, high-resolution, along-track sea level time series have been generated, and coastal sea level trends have been computed over a 14-year time span (from {J}uly 2002 to {J}une 2016). {I}n this paper, we focus on a particular coastal site where the {J}ason track crosses land, {S}enetosa, located south of {C}orsica in the {M}editerranean {S}ea, for two reasons: (1) the rate of sea level rise estimated in this project increases significantly in the last 4-5 km to the coast compared to what is observed further offshore, and (2) {S}enetosa is the calibration site for the {TOPEX}/{P}oseidon and {J}ason altimetry missions, which are equipped for that purpose with in situ instrumentation, in particular tide gauges and a {G}lobal {N}avigation {S}atellite {S}ystem ({GNSS}) antenna. {A} careful examination of all the potential errors that could explain the increased rate of sea level rise close to the coast (e.g., spurious trends in the geophysical corrections, imperfect inter-mission bias estimate, decrease of valid data close to the coast and errors in waveform retracking) has been carried out, but none of these effects appear able to explain the trend increase. {W}e further explored the possibility that it results from real physical processes. {C}hange in wave conditions was investigated, but wave setup was excluded as a potential contributor because the magnitude was too low and too localized in the immediate vicinity of the shoreline. {A} preliminary model-based investigation about the contribution of coastal currents indicates that it could be a plausible explanation of the observed change in sea level trend close to the coast.},
