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.

Crustal deformation strain rate grids, including fields and maps, are level 4 products constructed from steady-state geodetic velocities calculated over interseismic periods. Strain rate grids are based on weekly residual displacements relative to an underlying interseismic fault slip model using the methodology of Klein et al. (2019). Currently, limited to horizontal/2-D grids.
