Fluctuations in the local Newtonian gravitational field present a limit to high precision measurements, including searches for gravitational waves using laser interferometers. In this work, we present a model of this perturbing gravitational field and evaluate schemes to mitigate the effect by estimating and subtracting it from the interferometer data stream. The resulting improvement in the detector sensitivity should allow, for the first time, terrestrial interferometers to detect gravitational radiation from cosmological sources.
