Polar Motion Data of International Polar Motion Service
Entry ID: NAOMIZI-2


Summary
Abstract: Acting as the international polar motion measurement service(IPMS), this
international joint measurement of longitude and latitude was carried
out from 1962 to 1988.

The coordinate values of polar motion(X, Y) and the change in the
length of one day(L/D) were measured in this file. The IPMS
central station(Mizusawa) recorded this data using diurnal values
with the units of angular second and microseconds of time.
