Abstract
Astronomically-forced tides influence ocean surface height and currents on timescales of minutes to years.Tides contribute to ocean mixing (Munk & Wunsch, 1998) and mean flows (Loder, 1980), ice sheet and sea ice dynamics, and melting of ice shelves and marine terminating glaciers (Laurie Padman et al., 2018).Tidal signals must be accurately removed when calculating long-term trends in ocean surface height from tidally aliased satellite altimetry measurements (Smith et al., 2000), and the tidal component of ocean circulation must be removed for analyses of ship-based current measurements (Carrillo et al., 2005).Several models have been made publicly available to predict tides on global (Stammer et al., 2014) or regional (e.g., L. Padman & Erofeeva, 2004) scales.Each model contains only information about the complex coefficients of tidal constituents, and therefore requires software to extract and manipulate the data into values of tidal height or transport.The MATLAB package presented here is available at https://github.com/chadagreene/Tide-Model-Driverand offers an alternative to similar programs that are available in Fortran and Python (available at https://www.tpxo.net/otpsand https://github.com/tsutterley/pyTMD,respectively).
