Getting Assets into an NCAR-Managed Repository

Submitting or depositing your digital assets to be archived at an open repository can help in fulfilling data management plan requirements by ensuring the digital assets are shared openly and can be accessed publicly. The repository can also assist in facilitating the preservation and stewardship of the digital assets, so that the digital assets are available for long-term use/reuse.

Please note that to be eligible to deposit your datasets with an NCAR-managed repository, you will need to be one of the following categories:

  • NCAR staff
  • Officially appointed NCAR affiliated scientists

UCAR Community Program (UCP) Staff and NCAR External Collaborators are considered on a case by case basis.

The following diagram demonstrates how to determine the best option for archiving a digital asset.

Required Steps to Request Submission with NCAR-Managed Repositories

Step 1: Submit a request for repository support using the NCAR Dataset Submission Request System.
In return you will receive:
  • A repository recommendation for your request from the DASH team.
  • Contact from the DASH consulting service if there are questions regarding your request.
Step 2: If a data management plan (DMP) was required by your funding agency, please inform the Data Curation & Stewardship Coordinator.

If you have other questions or would like to learn more about archiving your digital assets with an NCAR-managed repository, please contact us.

  1. DASH Metadata is the official documentation method for sharing asset information via DASH Search and for describing the assets that will be submitted to DASH Repository for archive. For more information, please see Sharing Your Data page.

  2. High Performance Storage System (HPSS) is not considered as a open repository. For further information regarding the comparison between a HPSS and an open repository, please see the Frequently Asked Questions page.
