Abstract:According to the high consistency between the observed and theoretical data of the crustal deformation incremental value, we take the ratio of daily change amplitudes as a factor to detect scale changes. The method is used on most tidal deformation observation data in which the correlation coefficient is higher than 70%. Only one day’s data is needed to detect both the grid change and the graded change of the scale. Correcting data leads to different results, indicating that it is important to detect the change of scale and correct the data before analysis.
