High-frequency Earth rotation parameters estimated from VLBI observations during CONT campaigns
The Desai–Sibois high-frequency Earth rotation parameter (HF-ERP) model provides one of the most detailed descriptions of diurnal and sub-diurnal variability up to date. However, it still underrepresents short-period signals, underscoring the need for reliable, observation-based...
