U-PASS Instructions – PALSAR proposals

Proposals for access to PALSAR data are submitted on-line through the User-Proposal Application Submission System (U-PASS). The proposal process is designed to be short and simple. If you already have an ASF DAAC URSA log-in and password, you may log into U-PASS using the same information. If not, click the register button to create a user name and password. There are 5 steps in submitting a U-PASS proposal.

Description of the Steps in a U-PASS proposal:

  1. Agree to highlights of the ALOS End User License Agreement
    • Researchers are required to agree to only use the data for their own peaceful purposes and not to reproduce the data.
  2. Provide title and research objectives for proposal
    • Research objectives should be several sentences to a short paragraph in length describing how you plan to use the data. You will also need to provide your user type (US Government, academic institution, etc.) and your research subject area.
  3. List co-PIs associated with your project
    • Name, organization, and e-mail address (e-mails are optional for co-PIs)
  4. Provide information about your data requirements. If no information is provided, then the proposal is viewed as requesting data pool access only (the first data type listed).
    There are three different types of data:
    • ASF Datapool
      • All users are given access to the ASF Datapool, which contains all ALOS PALSAR data purchased for approved proposals and ALOS PALSAR data obtained using the NASA TDRS system.
    • Data from ASF Enterprise catalog
      • The ASF Enterprise archive contains all ALOS data acquired over the Americas, as well as some data from around the world. If you are interested in PALSAR data that has been archived by ASF Enterprise, please provide a list of the scene IDs. Seach ASF Enterprise catalog.
    • Data from JAXA catalog
      • JAXA maintains a catalog of all ALOS data that has been acquired. If you are interested in PALSAR data that has not been archived by ASF Enterprise, please provide a list of scene IDs, path numbers, and acquisition dates. The system accepts comma delineated and tab delineated formats. We suggest that you use the following website to search the JAXA archive.
  5. Review and submit proposal
    • The review page allows you to edit the content that you have entered into the proposal interface. Once you are satisfied, click the submit button at the bottom of the page.

A Word about Navigation

When submitting a proposal, you will move through the six steps by clicking on next and submit buttons. Numbered circles are also available at the bottom of the page, which help you move between the six proposal steps.

To begin creating a proposal, log in and select “create new proposal”. If you do not have a login, select register. You may either type the necessary information into the provided boxes, or you may copy and paste the information from a different application.

On the data requirements page, there links, one for each type of data request available (these are described above). Selecting the link for each type of data will bring you to a webpage where you can input the necessary information.

Proposal Approval

Once your proposal has been submitted, it will be reviewed first by the ASF User Support Office and then by NASA. Once the proposal is approved, you will be notified via e-mail.

Data that is in the ASF Enterprise archive will be transferred to the DAAC and placed within the ASF Datapool within 10 business days. The User Support Office will set up a data credit account for you on the DAAC for ordering processing of your data, if necessary.

Data requested from the JAXA archive will be ordered from JAXA by the User Support Office and then made available in the ASF Datapool once received.

Please contact the ASF User Support Office if you have any questions (907-474-6166, uso@asf.alaska.edu).
