IP1: Improved Tidal Dynamics and Uncertainty Estimation for Satellite Gravimetry (TIDUS)

PIs: Maik Thomas (FUB), Denise Dettmering (DGFI-TUM)

Research Objectives

  1. Quantify current ocean tide (OT) model uncertainties & impact on satellite gravimetry products
  2. Assess realistic errors for relevant OT constituents in different geographical regions
  3. Determine secondary ocean tide effects due to (i) minor tides, (ii) atmospheric tides, (iii) tidal loading
  4. Develop methods for achieving regional improvements of OT in critical regions



  • Statistical, region-dependent error assessment of OT
  • Detailed investigation of secondary tide effects and tidal loading
