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 HF-ERP series for ERP model validation a...

The global navigation satellite system (GNSS)-inverted terrestrial water storage (TWS) approach commonly adopts the PREM Earth model while neglecting crustal heterogeneity. This study systematically evaluates the impacts of different Earth models, including three spherically symmetric models (PREM, STW105, and AK135F)...

Global Navigation Satellite System Interferometric Reflectometry (GNSS-IR) has emerged as an effective noncontact technique for monitoring snow depth, a critical indicator of global climate change. However, heterogeneous topography and inconsistent surface reflectivity introduce spatial variability into reflected signa...
