The Arctic 2 km (kilometer) Tide Model (Arc2kmTM) is a barotropic ocean tide model on a 2x2 km polar stereographic grid, developed using the Regional Ocean Modeling System (ROMS). Arc2kmTM consists of spatial grids of complex amplitude coefficients for sea surface height and depth-integrated currents (“volume transports”) for 8 principal tidal constituents: 4 semidiurnal (M2, S2, K2, N2) and 4 diurnal (K1, O1, P1, Q1). See the Methods section for a description of model development. The Arc2kmTM gridded files are in binary format (see Arc2kmTM_FileFormat.pdf) and are designed to be used with the open-source software packages: the Matlab “Tide Model Driver” (TMD) toolbox, the Python “pyTMD” package, and the FORTRAN “OSU Tidal Prediction Software” (OTPS). These packages allow the user to browse the model for different constituents, and to make tidal predictions for any time at any location within the model domain.
