• A Spectrally Consistent Globally Defined Geodetic Mean Dynamic Ocean Topography 

      Siegismund, FrankORCIDiD (Journal of Geophysical Research: Oceans, 2020)
      The space-borne geodetic temporal mean dynamic topography (MDT) is obtained from the difference of altimetric mean sea surface (MSS) h and the geoid height N. With the geostrophic surface currents obtained from its gradient, ...
    • Temporal Variations of the Marine Geoid 

      Siegismund, F.ORCIDiD; Köhl, A.ORCIDiD; Rummel, R.; Stammer, D.ORCIDiD (Journal of Geophysical Research: Oceans, 2020-11-08)
      The effects of temporal changes in the marine geoid on estimates of the ocean dynamic topography are being investigated. Influences from mass redistribution due to changes of land hydrology, ice sheets, glacial isostatic ...
