Abstract :
In this paper, Changes in length of day (ΔLOD) are obtained through the processing of the 2009.1-2010.11 VLBI data; the time series of distance of the Moon and Earth obtained from Jet Propulsion Laboratory (JPL) ephemeris are calculated. Trend of ΔLOD and the Earth-to-Moon distance are removed, and the periods of them are calculated with spectral analysis. The correction between the Earth-to-Moon distance and the periodical components of ΔLOD extracted by wavelet analysis is analyzed.
