Common-mode variability and the limits of rainfall-only prediction in short-term PPP-GNSS vertical coordinates at four CORS stations in Western Java
Abstract Short-term vertical coordinates from daily static Precise Point Positioning (PPP) may contain environmental signals, but they are also sensitive to processing choices, station effects, and network-wide errors. This study re-evaluates whether local antecedent rainfall provides out-of-sample predictive informati...
