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.

    This paper examines the development of the stratospheric polar vortex ??ing National Meteorological Center data ??ring fall and early winter in the Northern Hemisphere during 1991-92, and in the Southern Hemisphere during 1992.
    Surface Temperature Estimation Over Land Using Satellite Microwave Radiometry
    Jan 1, 1993
    Njoku, E. G., 1993, "Surface Temperature Estimation Over Land Using Satellite Microwave Radiometry", https://hdl.handle.net/2014/34981, UNKNOWN, JPL Open Repository
    Surface temperature is an important parameter of the physical processes that govern the fluxes of energy and water at the biosphere-atmosphere interface. The energy and water fluxes have major influences on the Earth's weather and climate.
    Molecular Hydrogen-Rich Interstellar Ice
    Jan 1, 1993
    Dissly, R.; Allen, M.; Anicich, V., 1993, "Molecular Hydrogen-Rich Interstellar Ice", https://hdl.handle.net/2014/35240, Nature, JPL Open Repository
    While molecular hydrogen is by far the most abundant gas phase molecule in interstellar dark clouds, the extreme volatility of H2 suggests that it has a relatively low abundance in grain volatile mantles, thought to be composed largely of amorphous water ice.
