NASA’s Physical Oceanography Distributed Active Archive Center (PO.DAAC) released the Harmonic Constants for Baroclinic Tide Prediction dataset produced by Edward Zaron (Oregon State University). This dataset provides sea surface height and ocean surface currents associated with the predictable astronomical tide at the M2, S2, N2, K1, and O1 frequencies. The tidal harmonic constants, in-phase and quadrature with respect to the equilibrium potential, are provided on a latitude/longitude at 1/20-deg resolution. Using the software available in the documentation, the dataset can be used to predict baroclinic tidal sea surface height and surface ocean currents at arbitrary time and location throughout the world oceans.
For more details, please see documentation on the dataset landing page.
