Description

Making Earth System Data Records for Use in Research Environments (MEaSUREs) empowers the research community to participate in developing and generating data products that complement and augment NASA produced and distributed Earth science data products. NASA's Enhanced Solid Earth Science Earth Science Data Record (ESDR) System (ESESES) continues and extends mature geodetic data product generation and archival as part of the MEaSUREs SESES project providing new, multi-decade, calibrated and validated geodetic-derived ESDRs obtained by the Scripps Institution of Oceanography (SIO) and Jet Propulsion Laboratory/California Institute of Technology (JPL/Caltech). These data-derived products include continuous multi-year high-rate GNSS, seismogeodetic, and meteorological time series, a catalog of transient deformation in tectonically active areas known for aseismic motion such as ETS with focus in Cascadia, and continuous estimation and cataloging of total near-surface water content derived from continuous GNSS time series over the continental U.S.

These GNSS earthquake displacement products are high-rate displacements generated by a combination of GNSS data and seismic instruments, are typically 1 sample per second or greater, and are used to measure ground motions when earthquakes occur. These tar-compressed files include descriptive (.txt), metadata (.meta), figure (.png and .eps), and binary data files (.mseed) for GNSS displacements, seismogeodetic displacements, and seismogeodetic velocities.
