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.

    Delete Dataverse

    Are you sure you want to delete your dataverse? You cannot undelete this dataverse.

    Radar Investigations of Asteroids
    Aug 1, 1993
    Ostro, S., 1993, "Radar Investigations of Asteroids", https://hdl.handle.net/2014/34768, ['XXIV URSI General Assembly', 'Kyoto, Japan'], JPL Open Repository
    Resolution of an asteroid's echoes in Doppler frequency and/or time delay provides 1-D or 2-D images, and hence direct measurements of the asteroid's size and shape even though its angular extent is tiny compared to that of the radar beam.
    Structural Safety of a Hubble Space Telescope Science

    Way, JoBea; Bachman, Jennifer E.; Paige, David A., 1993, "(abstract) Sensitivity to Forest Biomass Based on Analysis of Scattering Mechanism", https://hdl.handle.net/2014/34934, Tokyo, Japan, JPL Open Repository
    The estimation of forest biomass on a global scale is an important input to global climate and carbon cycle models. Remote sensing using synthetic aperture radar offers a means to obtain such a data set. Although it has been clear for some time that radar signals penetrate forest...
    Analysis and Simulation for a Spotlight-Mode Aircraft SAR in Circular Flight Path

    Jin, Michael Y.; Chen, Ming, 1993, "Analysis and Simulation for a Spotlight-Mode Aircraft SAR in Circular Flight Path", https://hdl.handle.net/2014/34788, ['IGARSS: Better Understanding of Earth Environment', 'Tokyo, Japan'], JPL Open Repository
    A wide azimuth beam SAR can offer higher resolution or wider azimuth viewing angle; two factors that help better characterize the backscattering property of targets for various science applications. One disadvantage of wide beam SAR is that a much higher pulse repetition frequenc...
