Earth Rotation and Its Parameters
, 2023 The Earth is under continuous influence of external attractive forces of the Sun and Moon, as well as an internal coupling between the Earth’s core and mantle and mass movements. This is why its rotation is not uniform.

Estimation of Earth Rotation Parameters and Prediction of Polar Motion Using Hybrid CNN–LSTM Model
Remote Sensing, 2023 The Earth rotation parameters (ERPs), including polar motion (PMX and PMY) and universal time (UT1-UTC), play a central role in functions such as monitoring the Earth’s rotation and high-precision navigation and positioning.

Earth rotation parameter estimation from LLR [PDF]
Advances in Space Research, 2022 Lunar Laser Ranging (LLR) measures the distance between observatories on Earth and retro-reflectors on Moon since 1969. In this paper, we estimate the Earth Rotation Parameters (ERP; terrestrial pole offsets, x_P and y_P , and Earth rotation phase, DeltaUT1) using LLR data.
