metadata.name: dc.description.abstract
metadata.value: The paper presents results of modeling various variations of the Universal Time (UT1).
  To develop a variation models, UT1 observations from 1901 to 2020 published by the International
  Earth Rotation and Reference Systems Service (IERS) were used. Using the
  developed method, the main variations are identified from the diverse spectrum of irregularities
  in the Earth’s rotation, the models of which are presented as a superposition of a
  limited number of harmonic components. The results obtained in this paper are important
  for improving the accuracy of predictions of Universal Time.
