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 include 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

    (abstract) A Brief, Selective Review of Thermal Cycling Fatigue in Eutectic Tin-Lead Solder
    Oct 25, 1993
    Winslow, J. W.; Silveira, C. de, 1993, "(abstract) A Brief, Selective Review of Thermal Cycling Fatigue in Eutectic Tin-Lead Solder", https://hdl.handle.net/2014/35416, Las Vegas, NV, JPL Open Repository
    This paper reviews selected parts of the current literature relevant to thermo-mechanical fatigue mechanisms in eutectic tin-lead solder, and suggests a general outline to account for some observed failures. The field is found to be complex. One recent experimental study finds so...
    (abstract) A Broad-Band Microseismometer for Planetary Applications
    May 1, 1992
    Banerdt, W.B.; VanZandt, T.; Kaiser, W.J.; Kenny, T.W., 1992, "(abstract) A Broad-Band Microseismometer for Planetary Applications", https://hdl.handle.net/2014/35468, Pasadena, CA, JPL Open Repository
    There has recently been renewed interest in the development of instrumentation for making measurements on the surface of Mars. This is due to the Mars Environmental Survey (MESUR) Mission, for which approximately 16 small, long-lived (2 to 10 years), relatively inexpensive surfac...
    (abstract) A Comparison Between Measurements of the F-layer Critical Frequency and Values Derived from the PRISM Adjustment Algorithm Applied to Total Electron Content Data in the Equatorial Region
    Mar 20, 1994
    Mannucci, A. J.; Anderson, D. N.; Abdu, A. M., 1994, "(abstract) A Comparison Between Measurements of the F-layer Critical Frequency and Values Derived from the PRISM Adjustment Algorithm Applied to Total Electron Content Data in the Equatorial Region", https://hdl.handle.net/2014/33459, Bali, Indonesia, JPL Open Repository
    The Parametrized Real-Time Ionosphere Specification Model (PRISM) is a global ionospheric specification model that can incorporate real-time data to compute accurate electron density profiles. Time series of computed and measured data are compared in this paper. This comparison c...
    (abstract) A Geomagnetic Contribution to Climate Change in this Century
    Dec 1, 1996
    Feynman, J.; Ruzmaikin, A.; Lawrence, J., 1996, "(abstract) A Geomagnetic Contribution to Climate Change in this Century", https://hdl.handle.net/2014/27354, San Francisco, CA, JPL Open Repository
    There is a myth that all solar effects can be parameterized by the sun spot number. This is not true. For example, the level of geomagnetic activity during this century was not proportional to the sunspot number. Instead there is a large systematic increase in geomagnetic activit...
    (abstract) A High Throughput 3-D Inner Product Processor
    Oct 7, 1996
    Daud, Tuan, 1996, "(abstract) A High Throughput 3-D Inner Product Processor", https://hdl.handle.net/2014/27359, Minneapolis, MN, JPL Open Repository
    A particularily challenging image processing application is the real time scene acquisition and object discrimination. It requires spatio-temporal recognition of point and resolved objects at high speeds with parallel processing algorithms. Neural network paradigms provide fine g...
    (abstract) A Ka-Band 0.5 m Circularily Polarized Microstrip Reflectarray
    Jan 6, 1997
    Huang, John, 1997, "(abstract) A Ka-Band 0.5 m Circularily Polarized Microstrip Reflectarray", https://hdl.handle.net/2014/26489, Hong Kong, JPL Open Repository
    The microstrip reflectarray antenna, being in the form of a flat reflector, has recently been investigated by several antenna researchers. This antenna, when compared to the conventional parabolic reflector, not only has the potential advantages of achieving smaller mass, smaller...
    (abstract) A Mini-Surge on the Ryder Glacier, Greenland
    Dec 15, 1996
    Joughin, I.; Tulaczyk, Slawek; Fahnestock, M.; Kwok, R., 1996, "(abstract) A Mini-Surge on the Ryder Glacier, Greenland", https://hdl.handle.net/2014/26514, SAn Francisco, CA, JPL Open Repository
    We have detected a dramatic short-term speedup of the Ryder Glacier, Greenland, using satellite radar interferometry. The accelerated flow represents a substantial, though short-lived, change in the ice discharge from the basin. We use the term
    (abstract) A Miniature, High-Sensitivity, Electron-Tunneling Accelerometer
    Nov 28, 1994
    Gabrielson, Thomas B.; Rockstad, Howard K.; Tang, Tony K., 1994, "(abstract) A Miniature, High-Sensitivity, Electron-Tunneling Accelerometer", https://hdl.handle.net/2014/33360, Austin, Texas, JPL Open Repository
    A prototype low-noise accelerometer has been fabricated with an electron-tunneling transducer. By measuring the tunneling current between an electrode on the proof mass and a feedback-controlled monitor electrode, very small accelerations can be detected with high responsivity. T...
    (abstract) A Polarimetric Model for Effects of Brine Infiltrated Snow Cover and Frost Flowers on Sea Ice Backscatter
    Jul 24, 1995
    Nghiem, S.V.; Kwok, R.; Yueh, S.H., 1995, "(abstract) A Polarimetric Model for Effects of Brine Infiltrated Snow Cover and Frost Flowers on Sea Ice Backscatter", https://hdl.handle.net/2014/33375, Seattle, WA, JPL Open Repository
    A polarimetric scattering model is developed to study effects of snow cover and frost flowers with brine infiltration on thin sea ice. Leads containing thin sea ice in the Artic icepack are important to heat exchange with the atmosphere and salt flux into the upper ocean. Surface...

    Jan 12, 1995
    Murphy, D.W.; Tengay, S.J.; Jauncey, D.L.; Preston, R.A.; Reynolds, J.E.; Meier, D.L.; Tzioumis, A.K.; Jones, D.L., 1995, "(abstract) A Relativistically Expanding Radio Source Associated with GRO J1655-40", https://hdl.handle.net/2014/33630, Tuscon, AZ, JPL Open Repository
    GRO J1655-40 was discovered as a new, bright X-ray source with the BATSE detector of the Gamma Ray Observatory (GRO) on July 27, 1994. During the subsequent radio outburst we completed VLBI synthesis imaging observations at a frequency of 2.29 GHz. An unprecedented angular motion...
