Abstract To estimate the loading correction, the convolution integral of tidal height with gravity Green's function is usually adopted. Therefore, two kinds of error sources should be discussed, i.e. errors produced by different earth models and errors due to the inaccuracy of the cotidal maps. Thus, the effect of different earth models on tidal correction was estimated by using different loading Love numbers and gravity Green function obtained on the basis of two different earth models, G-B and 1066 model. We also calculated the error caused by Schwidersky's cotidal map, by assuming the error of average tidal height to be 5 cm in 1°×1° grids, but yet the effect coming from the errors of local cotidal maps had not been taken into consideration in this work. In carrying out this calculation, the results of tidal height errors in adjacent ocean around station, harmonic coefficient errors in open ocean and a truncation error are discussed respectively.
