The phase difference of the A-D pair of Omega had been observed continuously from February 1, 1974 till January 31, 1976 at the Faculty of Fisheries of Hokkaido University (41°48.'4 N, 140°43.'3 E). Fourier's analysis of these data was carried out and we determined the amplitudes a_n and hases β_n from the equation: PPC=a_0+Σ^^<12>__<n=1>a_nsin(nθ+β_n) (θ: U.T.). These coefficients are shown in Fig.2 (a), (b), (c) and Fig.3 and the correlation between coefficients a_n of the three PPC is expressed in Table 1. From the comparison of these coefficients, a considerable discrepancy was noted between the measured propagation correction (the measured PPC) and the theoretical propagation correction, but the measured PPC in 1974 and the one in 1975 were highly correlated except for the coefficient a_0.
