Abstract
Improvements in diurnal atmospheric and oceanic modeling are needed to calculate excitations of high‐frequency Earth orientation parameters.The study of Earth rotation variability is useful not only for practical application involving areas of astronomy, satellite geodesy, and spatial navigation, but also for obtaining constraints on parameters of Earth's internal structure. Modeling Earth rotation requires an interdisciplinary approach, involving subjects as diverse as magneto‐hydrodynamics, oceanography, atmospheric science, and celestial mechanics. When studying Earth rotation, we are dealing with its non‐constant rate and the position of the rotation axis, observed both from an inertial reference frame and from a frame rotating with the Earth.
