By combining a local ocean tide model near the Korean peninsula and a global ocean tide model, an accurate ocean tidal loading model of Korea is being constructed. We compare two global ocean tide models; NAO.99b and EOT11a, and then combine local ocean tide model together. Yellow sea is one of places of large tidal amplitude, and results in ocean loading of about 1 cm in the western and southern part of Korea. For the loading Green function, we use a new one calculated for the IASPEI earth model.mbine local ocean tide model together.
