Abstract

To compare sea level heights resulting from satellite altimeter observations and from tide gauge measurements it is necessary to know the tides, the sea surface topography and the geoid in the area under investigation. The paper discusses the characteristics of these components for a test area in the southern Baltic Sea. It is shown that the Baltic Sea is a proper area for such investigations. The method used for the comparison of the sea level heights as well as the results for a possible altimeter drift are presented.KeywordsTide GaugeGeoid ModelGeoid UndulationTide Gauge RecordTide Gauge DataThese keywords were added by machine and not by the authors.
