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.

    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.

    Remote Sensing of Seasonal and Annual Variation of Equatorial New Production: A Model for Global Estimates
    Jan 1, 1993
    Dugdale, R.; Wilkerson, F.; Halpern, D.; Chavez, F.; Barder, R., 1993, "Remote Sensing of Seasonal and Annual Variation of Equatorial New Production: A Model for Global Estimates", https://hdl.handle.net/2014/35376, Advances in Space Research, JPL Open Repository
    Sea-surface temperatures (SSTs) are strongly correlated with surface nitrate concentrations in coastal upwelling regions. Upwelling also occurs in the equatorial Pacific; correlations between temperature and nitrate concentration are strong. The University of Miami weekly average...

    Dynamics of Large Precision Space Structures for Structural Control
    Jan 1, 1993
    Wada, B., 1993, "Dynamics of Large Precision Space Structures for Structural Control", https://hdl.handle.net/2014/35436, JPL Open Repository
    This paper presents an overview of the challenges encountered in the prediction and ground test verification of structural dynamics for on-orbit control of large precision space structures.
    Vertical Ocean Loading Amplitudes From VLBI Measurements
    Jan 1, 1993
    Sovers, O., 1993, "Vertical Ocean Loading Amplitudes From VLBI Measurements", https://hdl.handle.net/2014/35464, UNKNOWN, JPL Open Repository
    Vertical ocean loading amplitudes are determined by analysis of IRIS geodetic VLBI data. Vertical ocean loading amplitudes can thus be inferred from VLBI data at a level which improves the overall model, but detailed assessment of individual tidal components is presently obscured...
    Dust Clouds Produced by Landings on Airless Bodies
    Jan 1, 1993
    Jaffe, L. D., 1993, "Dust Clouds Produced by Landings on Airless Bodies", https://hdl.handle.net/2014/35484, Icarus, JPL Open Repository
    Dust clouds can be produced by landings on airless planetary bodies, as well as on bodies with significant atmospheres.
    A Parametric Approach for the Geocoding of Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) Data in Rugged Terrain
    Jan 1, 1993
    Peter, M., 1993, "A Parametric Approach for the Geocoding of Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) Data in Rugged Terrain", https://hdl.handle.net/2014/35509, UNKNOWN, JPL Open Repository
    A geocoding procedure for remotely sensed data of airborne systems in rugged terrain is affected by several factors: buffeting of the aircraft by turbulances, variations in ground speed, changes in altitude, attitude variations, and surface topography.
