NSC Requests


Requests for allocations are now submitted and reviewed through the NCAR Resource Allocation System (RAS).

In general, fields on the RAS form should be self-explanatory; the information below is provided to clarify what information is needed in some of the fields. You may find it helpful to keep this page open when completing the new form.

Before you can submit the form, you will need to attach your Request Summary document. Please carefully follow these instructions when preparing that document. The file you attach can be no larger than 5 MB.

Open the new formIt will open in a separate window on a non-NCAR web site.

Log in with your UCAR/NCAR username and token if you have one.

Select the "NCAR NSC" Submission Opportunity

Is this a request for a new project or are you requesting the renewal of (or additional resources for) an existing project?

If this is a renewal of a previous NSC project, put your current CISL project code (e.g., NABC1234) in the "Request Number" field. 

Request Information

Title: Enter the title of the project for which you are requesting an allocation.

Abstract: Type or paste in a brief, self-contained description of your project (or course).

Keywords: No keywords are needed, so you can leave this blank.

Fields of Science

Only one Field of Science is required. (Additional fields of science will be disregarded.)

Check the "Primary" box.

Related Personnel

Use this section to designate your project lead and project admin. There should be only one project lead and one project admin.


  1. Select a role.
  2. Type a username, first name or last name in the “Search for people” field to find the individual to associate with that role.
  3. Select the individual to assign her or him to the role. 

DO NOT click “Create New User” unless you need to add an individual who is not already in the system. You will be able to add other users to the project once it has been created by sending requests to cislhelp@ucar.edu.

Caution: Do not delete your own record if you are designated as a project lead or project admin without first giving yourself another role in the project, such as "user." If you delete yourself from your only assigned role, you will be unable to make additional changes.
