01Description
Calendar-year mean position of Earth's rotation pole and its year-over-year drift velocity, computed mechanically from the IERS observed series (C01 through 1961, C04 from 1962). The mean pole path is the cleanest view of secular polar drift and of the departures of the recent decades.
