Modelling the sea level variations for the unification of altimetry missions Original Research Article

Regional single-mission models for the interannual and medium-term sea level variability are constructed in the Mediterranean Sea from altimetry data using statistical methods. Their estimated accuracy is a few centimetres at spatial scales of 50 Kilometres and at monthly time scales. The single-mission model is used to check bias and drifts between multi-mission sea surface height data. The extrapolated model constructed from sea-surface height and sea-surface temperature using the sea-surface temperature as predictor allows a comparison of non-simultaneous multi-mission data.
