CONUS crustal vertical velocities 2007-2017

This dataset includes vertical velocity fields derived from Global Positioning System (GPS) daily positions from 2007-2017, in the IGS08 reference frame. Residual velocities after removing glacial isostatic adjustment model (ICE6GD), elastic deformation due to GRACE-derived hydrologic loading, and Earth's geocenter motion are also presented. Description of data, methods, and results are documented in the following peer-reviewed publication:
