The JPL Open Repository (JOR) replaced the JPL Technical Report Server (TRS) in 2023. It is a repository for digital copies of technical publications authored by JPL employees. It includes journal articles (the Final Accepted Version), meeting papers, presentations, and other publications cleared for external distribution from 1992 to the present. It also includes research datasets from 2022 on.

Years covered: 1992 to the present.
  • 1992-2021 records were originally on the JPL Technical Report Server (TRS) on Dspace system; those records were migrated to Dataverse in 2022.
  • Records with publication date 2022 or later are native to the Dataverse.
  • Data sets: 2022 to present
  • There are a few pre-1992 records. Those were added to the system on a case-by-case request basis.

  • Persistent IDs (PIDs):
  • 1992-2021 records have Handles
  • 2022 and later records have Digital Object Identifiers (DOIs).
    • Featured Dataverses

    In order to use this feature you must have at least one published dataverse.

    Publish Dataverse

    Are you sure you want to publish your dataverse? Once you do so it must remain published.

    Publish Dataverse

    This dataverse cannot be published because the dataverse it is in has not been published.

    Satellite Radar Interferometry for Monitoring Ice-Sheet Motion: Application to an Antarctic Ice Stream
    Jan 1, 1993
    Goldstein, R. M.; Engelhardt, H.; Kamb, B.; Frolich, R. M., 1993, "Satellite Radar Interferometry for Monitoring Ice-Sheet Motion: Application to an Antarctic Ice Stream", https://hdl.handle.net/2014/35692, Science, JPL Open Repository
    As a new means of monitoring the flow velocities and grounding-line positions of ice streams, which are indicators of response of the Antarctic and Greenland ice sheets to climatic change or internal instability, the method of satellite radar interferometry (SRI) is here proposed...
    Ultra-High Spectral Resolution Observations of Fragmentation in Dark Cloud Cores
    Jan 1, 1993
    Velusamy, T.; Langer, W.; Kuiper, T; Levin, S.; Olsen, E., 1993, "Ultra-High Spectral Resolution Observations of Fragmentation in Dark Cloud Cores", https://hdl.handle.net/2014/35820, JPL Open Repository
    This paper presents new evidence of the fragmentary structure of dense cores in dark clouds using the high resolution spectra of the carbon chain molecule CCS transition (J subscript N = 2 subscript 1 - 1 subscript o) at 22.344033 GHz with 0.008 km s superscript -1 resolution.
    A Simple Theory of Capillary-Gravity Wave Turbulence
    Jan 1, 1993
    Glazman, Roman E., 1993, "A Simple Theory of Capillary-Gravity Wave Turbulence", https://hdl.handle.net/2014/36053, Journal of Fluid Mechanics, JPL Open Repository
    Employing a recently proposed "multi-wave interaction" theory [JFM, 243, 623-625], spectra of capillary-gravity waves are derived. This case is characterized by a rather high degree of nonlinearity and a complicated dispersion law. The resultant absence of scale invariance makes...
    An Investigation of the Interrelationships Between Linear and NonLinear Polarizabilities and Bond Length Alternation on Connugated Organic Molecules
    Jan 1, 1993
    Gorman, C. B.; Marder, S. R., 1993, "An Investigation of the Interrelationships Between Linear and NonLinear Polarizabilities and Bond Length Alternation on Connugated Organic Molecules", https://hdl.handle.net/2014/36570, UNKNOWN, JPL Open Repository
    A computational method was devised to explore the relationship between charge separation, geometry, molecular dipole moment, polarizability, and hyperpolarizabilities in comjugated organic molecules. It is shown that bond length alternation (the average difference in length betwe...
    The Application of Massively Parallel Computation to Integral Equation Models of Electromagnetic Scattering
    Jan 1, 1993
    Cwik, T.; Geijn, R. van de; Patterson, J., 1993, "The Application of Massively Parallel Computation to Integral Equation Models of Electromagnetic Scattering", https://hdl.handle.net/2014/36559, Journal Optical Society A, JPL Open Repository
    Integral equation methods are widely used in the analysis and design of electromagnetic systems.
    Mars Observer System Thermal Vacuum Test and Its Cost Saving Approach
    Jan 1, 1993
    James Fu; Timothy Larson, 1993, "Mars Observer System Thermal Vacuum Test and Its Cost Saving Approach", https://hdl.handle.net/2014/36496, ['14th Aerospace Testing Seminar: Spacecraft Testing & Cost Saving', 'Manhattan Beach, CA'], JPL Open Repository
    The Mars Observer spacecraft underwent a successful system thermal vacuum (STV) test in March 1992, meeting all five primary objectives. This paper presents a description of the spacecraft and the test configuration, as well as a discussion of the test results and how the test ob...
    Passive Microwave Remote Sensing for Land Resources
    Jan 1, 1993
    Njoku, E. G., 1993, "Passive Microwave Remote Sensing for Land Resources", https://hdl.handle.net/2014/34979, UNKNOWN, JPL Open Repository
    Spaceborne microwave radiometry is an important technique for obtaining global estimates of parameters important to Earth's hydrologic cycle, land resources, environmental monitoring, and climate. They key physical processes involved in these applications are the land-atmosphere...
