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.

    IRAS Colors Within M31; Evidence for Deficiency of Very Small Grains?
    Jan 1, 1993
    Xu, C.; Helou, G., 1993, "IRAS Colors Within M31; Evidence for Deficiency of Very Small Grains?", https://hdl.handle.net/2014/36609, The Astrophysical Journal, JPL Open Repository
    Significant differences are found in the IRAS color-color diagrams of small regions within the disk of M31 compared to Galactic cirrus, most noticeably demonstrated by a trend of low surface brightness ratio.
    Retrieval of Surface Directional Reflectance and Hemispherical Albedo Using Multi-angle Measurements, I. Ground Level Observations

    Knowledge of the directional reflectance properties of natural surfaces such as soils and vegetation canopies is essential for classification studies and canopy model inversions. Atmospheric correction schemes, using various levels of approximation, are described to retrieve surf...
    Navigating the Magellan Aerobrake
    Jan 1, 1993
    Giorgini, J.; Wong, S.; You, T-H., 1993, "Navigating the Magellan Aerobrake", https://hdl.handle.net/2014/36613, UNKNOWN, JPL Open Repository
    The Magellan spacecraft has been aerobraked into a 197 x 541 km near-circular orbit around Venus from which it is conducting a high-resolution gravity mapping mission. This was the first interplanetary aerobrake maneuver and involved flying the spacecraft through the upper reache...
    One Millimeter Horizontal Precision Over a 41 Km Baseline Using P-Codeless Data
    Jan 1, 1993
    Meehan, Thomas K.; Lindqwister, Ulf J., 1993, "One Millimeter Horizontal Precision Over a 41 Km Baseline Using P-Codeless Data", https://hdl.handle.net/2014/36615, UNKNOWN, JPL Open Repository
    High accuracy geodetic solutions at the few ppb level have become fairly standard with data from a global network of P-code Global Positioning System (GPS) receivers. Used as a measurement tool, it has numerous scientific applications including the monitoring of crustal motion, v...
    The Global Topography Mission
    Jan 1, 1993
    Farr, T.; Evans, D.; Zebker, H.; Harding, D.; Bufton, J.; Dixon, T.; Vetrella, S.; Gesch, D., 1993, "The Global Topography Mission", https://hdl.handle.net/2014/36627, UNKNOWN, JPL Open Repository
    An accurate description of the surface elevation of the Earth is of fundamental importance to many branches of Earth science. A number of working groups have considered the characteristics of the available digital topographic data base and found that there are significant deficie...
    Distributions of the Interplanetary Magnetic Field Revisite
    Jan 1, 1993
    Feynman, J.; Ruzmikin, A., 1993, "Distributions of the Interplanetary Magnetic Field Revisite", https://hdl.handle.net/2014/36626, UNKNOWN, JPL Open Repository
    The adequacy of the power spectrum to characterize the variations of a parameter depends on whether or not the parameter has a Gaussian distribution. We here perform very simple tests of Gaussianit on the distributions of the magnitudes of the interplanetary magnetic field, and o...
