Note The global data is provided in a netCDF format. The format of the data: lon - the longitudinal position; lat - the latitudinal position; amplitude - the tidal amplitude of the tidal constituent; phase - the tidal phase of the tidal constituent; real - the real component of the tidal constituent; and imag - the imaginary component of the tidal constituent.

Abstract

EOT20 is the latest in a series of global ocean tide models developed at DGFI-TUM. EOT20 is created using residual tidal analysis of multi-mission altimetry data from the period of 1992 to 2019. Eleven satellite altimetry missions are used and the FES2014b tide model used as the reference model for the residual tidal analysis. The model extends throughout the global ocean, with EOT20 ranging from 66°S to 66°N with FES2014b being used to fill in the higher latitudes. The model provides data about the amplitudes and phases as well as the real and imaginary components of seventeen tidal constituents for the global ocean. These tidal constituents are: 2N2, J1, K1, K2, M2, M4, MF, MM, N2, O1, P1, Q1, S1, S2, SA, SSA and T2. Both the ocean and load tide atlases are provided with a spatial resolution of 1/8 degree.
