Implication

Randomized trial demonstrates significant noise reduction in InSAR data using GPS-based corrections, suggesting enhanced applicability for atmospheric modeling.

Key Points

This research aims to develop a model for correcting atmospheric effects on InSAR measurements using GPS data to improve accuracy in detecting tectonic or volcanic displacements.
Utilized an Iterative Tropospheric Decomposition (ITD) model to differentiate and correct tropospheric signals.
Conducted tests to evaluate the effect of GPS station spacing on correction performance.
Applied the framework to Sentinel-1A interferograms in Southern California and Southern England.
Achieved noise reduction of approximately 45–78% with a sparse GPS network (50–80 km spacing).
Demonstrated a 50% improvement in accuracy over previous correction methods.
Validation indicated when and where corrections were feasible based on GPS data.
