Values of the Chandlerian period and the damping coefficient of the polar motion are calculated for every ten years from 1900.0 to 1970.0, using a method developed by Sekiguchi (1966). The damping coefficient is variable between 0.074 and 0.008 (yr)−1 through this period, and correlative with the variation of the Chandlerian period, as Sekiguchi (1961) theorized.
