Our comprehensive global tidal dataset is now available to all Datamesh users, delivering current and elevation data for more than 400 million locations across coastal regions, islands and continental shelves worldwide.
Global coverage with local detail – more than 1,000 overlapping coastal domains covering major coastlines and remote islands at 400m resolution.
Downscaled from TPXO Atlas using OTIS Tidal Inversion Software with barotropic boundaries from TPXO9 Atlas v5 and bathymetry from GEBCO.
14 tidal components – includes major constituents (M2, S2, N2, K2, K1, O1, P1, Q1) plus longer period and shallow water components (MM, MF, M4, MN4, MS4, 2N2).
Flexible access – tidal predictions available for any time period using efficient Datamesh API queries.
Ideal for prescribing your hydrodynamic model boundary conditions, survey planning, navigation, or to combine with oceanic current reanalyses.
