Use of the Oregon State University Tidal Inversion Software (OTIS) to Generate Improved Tidal Prediction in the East-Asian Seas

Abstract

The Oregon State University (OSU) Tidal Inversion Software (OTIS) is being automated, tested and used to generate tidal solutions in the East-Asian Seas (EAS) region. This effort was undertaken to improve the tidal solutions within a relocatable version of the Navy Coastal Ocean Model (NCOM). Tests were conducted within the EAS and with a smaller domain within the EAS, the Yellow Sea, to look at the effects on OTIS of a number of inputs including: (1) increasing grid resolution, (2) using more accurate bathymetry, (3) assimilating International Hydrographic Office (IHO) tide station data (as well as tidal data derived from the TOPEX altimeter data), (4) increasing the number of representers used for data assimilation, and (5) increasing the number of tidal constituents being solved for. The tidal solutions generated with OTIS were validated against IHO tide station data in the different areas.
