On the NAS Data Portal submission site, you can submit a dataset to share with others and view a list of all of the datasets you have already submitted. Please note that currently, only NAS users can submit datasets. Additionally, you as the data owner will be responsible for maintaining backup copies of the dataset. While NAS will keep the data as current and consistent as possible, there might be issues with other uncertainties beyond our control. We recommend you copy critical files to the tape archives.

Note: The Data Portal is currently close to its storage capacity. Depending on the size of your dataset, the Data Portal team may not be able to deploy it as this time. We are, however, actively working to acquire more storage, and are currently building a wait queue for researchers who want to submit their datasets for sharing through the Data Portal. Please go ahead and submit your dataset to the Data Portal, and we will contact you when we are able to proceed with this deployment. Also, if you have funds available to support storage for your dataset, please contact the Big Data Team Lead, Shubha Ranjan, at shubha.ranjan@nasa.gov.

Submitting Your Dataset

To submit your dataset:

1. Review each type of dataset and its security requirements in NAS Data Portal: Overview.
2. Go to the NAS Data Portal dataset submission site.
3. Log in using your NAS username and password.
4. Select New Dataset in the menu.

The submission form will be displayed. This section describes each field of the form.

• For NASA-affiliated collaborators, you can provide just the email address.
• For non-NASA collaborators, you will need to provide an email address, first and last name, and the country of citizenship. You may also optionally provide a phone number. In addition, for non-NASA collaborators you will need to provide the ID number of the release document (e.g. SAA or SUA) for each specified collaborator, and the expiration date of that document; there is also a checkbox for you to acknowledge responsibility for obtaining the release documents. You may specify as many collaborators as you need. LaunchPad guest accounts will be set up for non-NASA collaborators, so that they can log into the Data Portal to access the restricted dataset.

Principal Investigator

Select the Principal Investigator (PI) for this project from the dropdown list, which includes the PIs for all of the projects you are assigned to. Once you submit the dataset, the PI will be notified; if approved, it will go to the NAS team for final validation and deployment on the Data Portal.

Name

Provide a name for your dataset. This name will be used to identify the dataset in email notifications.

Short Name

If your dataset is public (not restricted), provide a short project name for the dataset. This name will be used as the directory name for the dataset in the Data Portal's filesystem.

Description

Provide a description of your dataset, explaining what the data is, how it was generated, what it is used for, and so on.

Location

Specify the full path to the dataset on the /nobackup filesystem (all shared datasets must reside on one of the /nobackup filesystems). Ensure that all of the files are located in one top-level directory under public (for public) or private (for restricted). For example:

• /nobackupp8/username/public/datasetname/
• /nobackupp8/username/private/datasetname

Directory names in and under the top-level directory must not contain any of the following characters:
#$%^&*()+=\[\]:?~'\";)

The best way to copy your dataset files to a /nobackup filesystem is to use the shiftc command. This automates the required file striping.

Note: If it is not feasible to house all of your public dataset files on one filesystem as described above, please list one location in this field, and use the Notes field below to specify the additional locations. The NAS team will contact you to discuss the locations.

Processed

Check this box if the dataset contains processed data (where processed is defined as data that has been modified, reduced, filtered, or interpreted in some way).

Note: Public processed datasets that contain Scientific and Technical Information (STI) must have an approved NASA Form 1676B (per NASA Policy Directive (NPD) 2230.1), which must be uploaded when submitting this dataset (see the Uploaded 1676B field below). The form is available here: NASA Form 1676B (requires login to NASA's Access Launchpad)

Restricted

Check this box if the dataset is to be restricted to specified collaborators. Checking the box reveals an additional field:

Restricted Users: Specify the people you would like to share your dataset with. You may specify as many collaborators as needed, as described below.

Note: If your restricted dataset is to be shared with non-NASA collaborators, either a NASA Form 1676, or a Space Act Agreement (SAA), or Software Usage Agreement (SUA) will be required depending on the individuals it’s being shared with. If you need further assistance with setting up non-NASA collaborators, please contact the Data Portal team.

• For NASA-affiliated collaborators, you can provide just the email address.
   
• For non-NASA collaborators, you will need to provide an email address, first and last name, and the country of citizenship. You may also optionally provide a phone number. Additionally, for non-NASA collaborators, you will need to provide the ID number of the release document (e.g. SAA or SUA) for each specified collaborator, and the expiration date of that document. There is also a checkbox for you to acknowledge responsibility for obtaining the release documents. LaunchPad guest accounts will be set up for any non-NASA collaborators, so that they can log into the Data Portal to access the restricted dataset.

Notes

If you would like to convey any special notes about this dataset, include them here. This can be used to describe additional locations of dataset files, for instance.

Associated Websites

Provide one or more websites that pertain to this dataset, as needed.

Tags

Provide a comma-separated list of keywords (tags) that will be associated with your dataset on the Data Portal. Other users can search for your dataset using these tags.

No 1676B Needed

Form 1676B is required only for the following types of datasets:

• Public, processed datasets that include STI information
• Restricted datasets where foreign nationals are included as collaborators (refer to "excepted" data per NPD 2230.1).

Check this box to acknowledge that the dataset is not subject to form 1676B requirements; otherwise, you must upload a completed form using the provided file browser described below.

Uploaded 1676B

If your dataset requires Form 1676B, use this file browser to upload the completed form. (Note that neither this field nor the one above, No 1676B Needed, will be shown if the dataset is designated as a raw public dataset.)

Security Requirements

All datasets need to meet the security requirements listed on the form. Please ensure your dataset meets these requirements and check this box. See NAS Data Portal: Overview for details about security requirements for each data type.
