MEaSUREs SESES: GNSS-Derived Geodetic Time Series and Water Storage Change

Continental U.S. and global datasets provide multi-decade, calibrated geodetic Earth Science Data Records. The collection includes continuous high-rate GNSS, seismogeodetic, and meteorological time series, a catalog of transient tectonic deformation, and grids of total water storage change derived from GNSS data. These products are generated by the Scripps Institution of Oceanography and NASA's Jet Propulsion Laboratory under the MEaSUREs program.

Use Cases

• Monitoring aseismic slip events like Episodic Tremor and Slip (ETS) in Cascadia using the transient deformation catalog.
• Estimating changes in near-surface total water content over the continental U.S. from continuous GNSS time series.
• Analyzing long-term tectonic displacement and velocity from combined, cleaned GIPSY-GAMIT station position time series.
• Integrating high-rate GNSS and seismic data for seismogeodetic studies of earthquake processes.

Strengths

• Data is multi-decade, calibrated, and validated, indicating a long-term, quality-controlled record.
• Products are generated by authoritative institutions (Scripps Institution of Oceanography, NASA JPL).
• Cross-platform presence on Data.gov and NASA EarthData signals importance and official curation.

Limitations

• Column names and specific data structures are not provided in any source description.
• Exact temporal coverage, row counts, and file sizes are unknown across all platforms.
• The license is listed only as 'other-license-specified' without detailed terms.
