Plans for high accuracy computations of Earth rotation/polar motion excitations

Knowledge from atmospheric analyses and/or models is very important for calculations of the excitations of the Earth, including length of day, polar motion, and nutation, and has further consequences for understanding of the geophysical structure of the Earth’s interior, that is, mantle and core. With some of the nutation parameters especially dependent on the diurnal variability of the atmosphere’s equatorial angular momentum, it is important to seek the best series for such terms. We are grateful to the winners of the Descartes Prize for their nutation studies with having chosen our team for an award to study the relevant excitation functions.
