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.

3-dimensional station velocity estimates are direct products of MEaSUREs daily displacement time series analysis. A single station velocities (horizontal, vertical, and uncertainties) file is generated weekly in parallel with the daily displacement time series (combined weighted mean Jet Propulsion Lab and Scripps Institution of Oceanography, filtered and unfiltered products) by extracting velocities and uncertainties from the time series file headers. Uncertainties include the effects of colored noise in daily time series. The north, east and up velocities are assumed to be uncorrelated. Velocities are given only for stations with a minimum of 2.5 years of data. The reference frame is IGS14 (ITRF2014).
