Abstract
Ocean tide displacement corrections for most Chinese geodetic stations are not included in IERS standards. According to surface load deformation theory, we calculated ocean tide displacement corrections for Chinese geodetic stations by using CSR3.0 global ocean tide model and the result of Farrell Green's function. Some calculated results agree well with those published in IERS standards, so they can be used to monitor the crust deformation in high precision geodesy, especially in coast area.
