We report on a micro-gravity survey of the laboratories where the LNE's watt balance
experiment is being conducted, including the characterization of the Scintrex CG-5 relative
gravimeter used for this study. The results of the survey are compared with a model of the
gravity field generated by the local mass distribution. The ultimate goal is to transfer an
absolute measurement of g from one room to another with minimal uncertainty.
