The Geoid Monitoring Service is an NGS project tasked with recommending and building time-dependent quantities associated with geoid undulations, surface gravity, deflections of the vertical, geopotential numbers, and a digital elevation model. The first phase of this project is reaching completion, and users of the National Spatial Reference System (NSRS) will begin to see these attributes in NGS products and tools.
