The 5 kilometer (km) Arctic Ocean Tidal Inverse Model developed in 2004 (AOTIM5) is a barotropic tide model on a polar stereographic grid. AOTIM5 was created using the OSU Tidal Inversion Software (OTIS) package (https://www.tpxo.net/). Model development is described by Padman and Erofeeva (2004) (https://doi.org/10.1029/2003GL019003). The bathymetry grid is based on the original International Bathymetric Chart of the Arctic Ocean (IBCAO) bathymetry (Jakobsson et al., 2000; https://doi.org/10.1029/00EO00059). AOTIM5 consists of grids of sea surface height and depth-integrated currents (“volume transports”) for each of 8 tidal constituents; 4 semidiurnal (M2, S2, K2, N2) and 4 diurnal (K1, O1, P1, Q1). The first step in building AOTIM5 was development of the Arctic Ocean Dynamics-based Tide Model (AODTM5), which is also available at the Arctic Data Center (https://arcticdata.io/catalog/view/doi:10.18739/A2901ZG3N). That model was forced at open ocean boundaries by the TOPEX/Poseidon global barotropic tidal ...
