The structure of the bathymetry and tidal harmonic coefficient grid files for the models available here are consistent with the Oregon State University suite of global and regional tide model solutions (see and Thus, these models can also be run in Matlab with the TMD toolbox. Download the required model(s) from the OSU sites, then create a ‘Model’ file that names each of the necessary binary grid files. For example, the file, Model_tpxo7.2, is an ASCII file containing the following 3 lines:


These lines refer to the binary (OTIS format) files containing complex harmonic coefficient grids for height (h_tpxo7.2) and velocity (u_tpxo7.2), and the bathymetry grid file grid_tpxo7.2. For further information, see the README_TMD.pdf file.
