In order to reduce the tidal errors in the shallow water region, we established a global ocean tide model (NAO.99b) representing major 16 constituents with a spatial resolution of 0.5°. The key feature of this model is a fine-scale along-track tidal analysis of the TOPEX/POSEIDON data, the results of which are assimilated into a barotropic hydrodynamical model which account for the self-attraction and the loading effect accurately. Also we developed a high-resolution (1/12°) regional ocean tide model around Japan (NAO.99Jb) by assimilating both the TOPEX/POSEIDON data and the data of 219 coastal tide gauges. These models with a computer code for tidal loading calculation have been freely distributed via a web site to whomever interested including eodesits and ocennogrnnhers.
