Notes:

  • New Arctic data set, arctic9 (July, 2009), replaces the previous set (arctic8d).

    The tidal prediction system for the Canadian Arctic Archipelago developed by Dunphy et al. (2005) and Hannah et al. (2008) has been improved. The improvements include extension of the mesh south to include Frobisher Bay and southern Baffin Island, increased resolution in narrow channels such as Hell Gate, Cardigan Channel, and Penny Strait, and inclusion of the very narrow Bellot Strait. A detailed comparison with Hannah et al. (2008) shows that Baffin Bay is the most-improved region, and M2 is the most-improved constituent: the average rms error over all constituents is reduced by 3 cm, while the average rms error for M2 across all regions is reduced by 2 cm. Averaged over the entire model domain the rms error of the tidal constituents is about 17 cm for M2 and about (4, 7, 6, 3) cm for (N2, S2, K1, O1). The large M2 error is dominated by the errors in Frobisher Bay, where the M2 tidal amplitude is very large.
  • Five constituents available: M2, K1, N2, S2 and O1
