Implication

This research establishes a surface gravity network using high redundancy in measurements, suggesting effective strategies to mitigate noise problems.

Key Points

The surface gravity network demonstrates effective mitigation of traffic-induced noise at measurement sites, enhancing data accuracy.
With 498 stations, including 22 absolute gravity stations, the network spans a third of Colombia's area, significantly increasing gravity data availability.
Using both automatic and manual gravimeters increased measurement flexibility, achieving a typical uncertainty of ± 0.03 mGal.
Leave-one-out cross-validation tests validated the measurement robustness, indicating that residuals were statistically indistinguishable from zero.
