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

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

    Harris, A. W., 1993, "The Probable Ages of Asteroid Families", https://hdl.handle.net/2014/35814, ['Bul. American Astron. Society', 'Tokyo University', 'Tokyo, Japan'], JPL Open Repository
    There has been considerable debate recently over the ages of the Hirayama families, and in particular if some of the families are very ҹoungӮ It is a straightforward task to estimate the characteristic time of a collision between a body of a given diameter, d_o, by another body o...
    Fall Freeze-up of Sea Ice in the Beaufort-Chukchi Seas Using ERS-1 SAR and Buoy Data
    Jan 1, 1993
    Holt, B.; Winebrenner, B.; Nelson E. D., 1993, "Fall Freeze-up of Sea Ice in the Beaufort-Chukchi Seas Using ERS-1 SAR and Buoy Data", https://hdl.handle.net/2014/35937, ['EOS', 'American Geophysical Union', 'San Francisco'], JPL Open Repository
    The lowering of air temperatures below freezing in the fall indicates the end of summer melt and the onset of steady sea ice growth. The thickness and condition of ice that remains at the end of summer has ramifications for the thickness that that ice will attain at the end of th...
    High Temperature Superconductor Josephson Weak Links
    Jan 1, 1993
    Hunt, B. D.; Barner, J. B.; Foote, M. C.; Vasquez, R. C., 1993, "High Temperature Superconductor Josephson Weak Links", https://hdl.handle.net/2014/35494, ['Proceedings of the Electrochemical Society', 'Second Symposium of Low Temperature Electronics and High Temperature Superconducting', 'Honolulu, Hawaii'], JPL Open Repository
    High T_c edge-geometry SNS microbridges have been fabricated using ion-damaged YBa_2Cu_3O_(7-x) (YBCO) and a nonsuperconducting phase of YBCO (N-YBCO) as normal metals. Optimization of the ion milling process used for YBCO edge formation and cleaning has resulted in ion-damage ba...

    The Cassini spacecraft is being developed by the Jet Propulsion Laboratory (JPL) for theNational Aeronautics and Space Administration (NASA) to orbit and explore the planet Saturn, itsrings and satellites. Cassini will be launched on a Titan IV and boosted out of earth orbit by a...
    Implication of the January 1990 Volcanic Eruption on Io for Resurfacing Rates and Energetics
    Jan 1, 1993
    Johnson, T. V.; Matson, D. L.; Veeder, G. J.; Blaney, D. L.; Goguen, J.
