Accurate determination of dynamic topography (DT) is expected to quantify a realistic sea surface, with respect to its vertical datum, and in identifying sub-mesoscale features of ocean dynamics. This dataset contains DT derived using satellite altimetry (SA) along-track data from Sentinel- 3A (S3A), Sentinel-3B (S3B), and Jason-3 (JA3) for the period 2017‒2019 over the Baltic Sea with respect to a high-resolution marine geoid model (NKG2015). To assess the SA-derived DT accuracy they have been compared with DT derived from a tide gauge (TG) corrected hydrodynamic model (HDM). The HDM model contains the Nemo-Nordic NS01 data assimilated model developed by the Swedish Meteorological and Hydrological Institute (SMHI www.smhi.se) which has been corrected at the time and location of each SA pass and cycle utilizing hourly observation of 73 tide gauge stations over the Baltic Sea using the methodology described in "" paper by Mostafavi M. et al., (2023). The DT can alternatively be converted to Sea Surface Height (SSH) by adding the geoid height value derived from the NKG2015 geoid model available in the dataset.
