It is necessary to know the peculiarity of Omega phase difference all year round. The authors conducted a measurement on the subject of the phase difference of the A-C pair and C-D pair at the Faculty of Fisheries of Hokkaido University from January 1, 1975, till December 31, 1975. Fourier's analysis of these data was carried out and we determined the amplitudes a_n and phases β_n from the equation: PPC=a_0+Σ^^<12>__<n=1>a_nsin(nθ+β_n) (θ: U.T.) The difference between the measured propagation correction (the measured PPC), and the published predicted propagation correction is large on the whole. In connection with the C-D pair, the coefficient a_1 is small compared with other pairs and the measured PPC was largely affected by the other coefficients.
