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.

    A review of infrared readout electornics for space science sensors is presented. General requirements for scientific IR FPA readout are discussed. Specific approaches to the unit cell electronics are described with respect to operation, complexity, noise and other operating param...
    Particle Motion Near a Ring
    Jul 13, 1993
    Scheeres, D.J., 1993, "Particle Motion Near a Ring", https://hdl.handle.net/2014/35543, USA, JPL Open Repository
    The dynamics of a particle moving near a classical ring is studied under a Hill-type approximation. A classical ring is comprised of particles of equal mass arranged symmetrically about a massive central body, the particles having a uniform rotation rate.

    Sokolowski, W.; Jacobs, S.; Lane, M.; O'Donnell, T.; Hsieh, C., 1993, "Dimensional Stability of High Purity Invar 36", https://hdl.handle.net/2014/35527, San Diego, CA, JPL Open Repository
    High performance requirements for the Imaging Science Subsystem (ISS)/Narrow Angle Camera (NAC) instrument on the NASA/Jet Propulsion Laboratory (JPL) Cassini spacecraft impose very stringent demands for dimensional stability of metering rods in the camera's athermalizing system.
    C-Band Radar Backsctter of Sea Ice in The Weddell Sea, Antarctica During The Austral Winter of 1992
    Jul 12, 1993
    Hosseinmostafa, R.; Drinkwater, M.R.; Gogineni, S.P.; Dierking, W., 1993, "C-Band Radar Backsctter of Sea Ice in The Weddell Sea, Antarctica During The Austral Winter of 1992", https://hdl.handle.net/2014/35364, Pasadena, California, USA, JPL Open Repository
    A C-band ship-based scatterometer was used to measure the backscatter coefficient of sea ice in the Weddell Sea during June and July 1992. These are the first microwave scatterometer data ever to be collected in the Antarctic sea ice cover during the austral winter.
    Quantitative Relationships Between Net Volume Change and Fabric Properties During Soil Evolution
    Jul 12, 1993
    Chadwick, O.A.; Nettleton, W.D., 1993, "Quantitative Relationships Between Net Volume Change and Fabric Properties During Soil Evolution", https://hdl.handle.net/2014/35136, Townsville, Queensland, Australia, JPL Open Repository
    The state of soil evolution can be charted by net long-term volume and elemental mass changes for individual horizons compared with parent material. Volume collapse or dilation depends on relative elemental mass fluxes associated with losses form or additions to soil horizons.
