NTIP is an input in the fort.15 file that selects the astronomical forcing input type.

Parameter Summary

The following table is a summary of possible NTIP values, description, details, and other necessary input parameters and files.

NTIP Value Description Details Other Required Inputs
0 No Astronomical Forcing - NTIF = 0
1 Astronomical Tidal Potential Reconstructs the tidal elevation using the analytical formulation for the equilibrium tidal potential[1] NTIF > 0
2 Astronomical Tidal Potential plus Self-attraction and Loading (SAL) Tide[2] Reconstructs the tidal elevation by summing the contribution from the analytical formulation for the equilibrium tidal potential[1] with the contribution from the prescribed SAL constituent values found in the fort.24 file. NTIF > 0, fort.24 file
