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.

    HEAO 3 Observations of the Galactic Center 511 keV Line
    Jan 1, 1993
    Mahoney, W.; Ling, J.; Wheaton, W., 1993, "HEAO 3 Observations of the Galactic Center 511 keV Line", https://hdl.handle.net/2014/35291, JPL Open Repository
    This paper describes improved analysis algorithms which enabled HEAO 3 data to be reexamined for an assumed point source at the Galactic center.
    Transition Edge YBa_2Cu_3O_(7-x) Microbolometers for Infrared Staring Arrays
    Jan 1, 1993
    Foote, M.C.; Johnson, B.R.; Hunt, B.D.; Vasquez, R.P.; Barner, J.B., 1993, "Transition Edge YBa_2Cu_3O_(7-x) Microbolometers for Infrared Staring Arrays", https://hdl.handle.net/2014/35520, ['SPIE Superconducting Detectors', 'Los Angeles, CA'], JPL Open Repository
    A potentially important application of high-temperature superconducting microbolometers is infrared staring arrays. In many such staring arrays, sensitivity is more important than speed of response. Thus, it is desirable to design low-thermal-mass pixels that are thermally isolat...
    Extraction of Auxiliary Data from AVIRIS Distribution Tape for Spectral, Radiometric, and Geometric Quality Assessment
    Jan 1, 1993
    Meyer, P.; Green, R. O.; Chrien, T. G., 1993, "Extraction of Auxiliary Data from AVIRIS Distribution Tape for Spectral, Radiometric, and Geometric Quality Assessment", https://hdl.handle.net/2014/35589, UNKNOWN, JPL Open Repository
    Remotely sensed data are affected by system (sensor and platform), and scene related effects. For quantitative investigations the spectral, radiometric and geometric characteristics of the system and scene have to be known.
    The Hubble Space Telescope Extragalactic Distance Scale Key Project KK: Photometry of WFC Images of M81
    Jan 1, 1993
    Hughes, S.; Mould, B. MadoreJ.; Ferrarese, L.; Ford, H.; Freedman, W.; Hill, R.; Lee, M.; Graham, J.; Hoessel, J.; Huchra, J.; Illingworth, G.; Kennicutt, R.; Turner, A.; Stetson, P., 1993, "The Hubble Space Telescope Extragalactic Distance Scale Key Project KK: Photometry of WFC Images of M81", https://hdl.handle.net/2014/35988, JPL Open Repository
    This paper describes the Extragalactic Distance Scale Key Project for Hubble Space Telescope which aims to employ the Cepheid period-luminosity relation to measure galaxy distances out as far as the Virgo cluster.
    Investigation of Possible Electromagnetic Disturbances Caused by Spacecraft-Plasma Interactions at 4 R Subscript s Small Solar Probe
    Jan 1, 1993
    Okada, M.; Tsurutani, B.; Goldstein, B.; Brinca, A.; Matsumoto, H.; Kellogg, P., 1993, "Investigation of Possible Electromagnetic Disturbances Caused by Spacecraft-Plasma Interactions at 4 R Subscript s Small Solar Probe", https://hdl.handle.net/2014/36604, UNKNOWN, JPL Open Repository
    The proposed Small Solar Probe mission features a close approach to the sun with a perihelion of 4 R subscript s. Carbon molecules emitted from the spacecraft's heat shield will become ionized by electron impact and photoionization.
    Very Long Wavelength InxGal-xAs/GaAs Quantum Well Infrared Photodetectors
    Jan 1, 1993
    Gunapala, S. D.; Bandara, K. M. S. V.; Levine, B. F.; Sarusi, G.; Sivco, D. L.; Cho, A. Y., 1993, "Very Long Wavelength InxGal-xAs/GaAs Quantum Well Infrared Photodetectors", https://hdl.handle.net/2014/36500, UNKNOWN, JPL Open Repository
    We demonstrate the first long-wavelength (=20) quantum well infrared photodetector using non-lattice matched InGaAs/GaAs materials system. High optical gains (low capture probabilities) were achieved by using GaAs as a barrier material in this system.
    Global Low Harmonic Degree Models of the Seasonal Variability and Residual Ocean Tides from TOPEX/Poseidon Altimeter Data

    The large scale seasonal variability is estimated jointly with the mean sea surface and the ocean tide signal not recovered by the Cartwright and Ray ocean tide model.
    Tidal Disruption and the Appearance of Periodic Comet Shoemaker-Levy 9
    Jan 1, 1993
    Sekanina, Zdenek; Chodas, Paul W.; Yeomans, Donald K., 1993, "Tidal Disruption and the Appearance of Periodic Comet Shoemaker-Levy 9", https://hdl.handle.net/2014/36567, UNKNOWN, JPL Open Repository
    A unified model is presented that quantitatively interprets the observed characteristics of the nuclear train, the two dust trails, and the tail region of P/Shoemaker-Levy 9 in terms of a collisionally modified rotation velocity distribution of the comet's debris.
