ICESAT-2 ALTIMETRY AS GEODETIC CONTROL

This study presents 25 years of carefully processed gravity measurements from western France, offering a unique dataset to support investigations of long-term land motion and sea level change. The data are consistent with satellite-based observations and are made available for use in future geophysical and climate-related research.

Spotgins is a cooperative of several research groups producing a consistent and high-quality set of Global Navigation Satellite Systems (GNSS) daily position time series. Each group contributes to the global network using the same processing. The Spotgins series are valuable for the understanding of subtle deformations of the Earth's surface at the millimeter level that include tectonics, earthquakes, ground subsidence, post-glacial rebound, hydrological loading, and volcanic deformation.
