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.

    Lilienthal, G. W., 1993, "Pointing Mechanisms for the Shuttle Radar Laboratory", https://hdl.handle.net/2014/34879, Moffett Field, California, USA, JPL Open Repository
    In December of 1993, the Shuttle Radar Laboratory (SRL) is scheduled for launch on the first of its two missions. The SRL has three major radar instrument, two distributed phased-array antennas that make up the Spaceborne Imaging Radar-C System (SIR-S) and are capable of being el...
    Entrainment, Evaporation and Combustion of Drops in the Laminar Part of a Developing Mixing Layer
    May 1, 1993
    Fichot, F.; Bellan, J.; Harstad, K., 1993, "Entrainment, Evaporation and Combustion of Drops in the Laminar Part of a Developing Mixing Layer", https://hdl.handle.net/2014/34900, Boston, Massachusettes, USA, JPL Open Repository
    A model is formulated in order to simulate the development of a sheer layer between a flow of air and a flow of fuel drops in a carrier gas. A characteristic feature of this type of flow is the interaction between the drop and the large-scale vortices produced the shear layer.
