Abstract: Sea level change at the coast require high quality sea surface height time series. The main source of modern sea level measurements is provided by digital coastal tide gauges, which need regular calibration campaigns to ensure their precision & accuracy. There exist several types of tide gauges – Tide pole, Probe, Radar tide gauge,Pressure tide gauge, GNSS buoys, GNSS reflectometry. We propose a more complete assessment of tide gauges (combined solution + biases + uncertainties), by using a combination formulation of the problem along with a Variance Component Estimation method.
