How to access a restricted data set

I alluded earlier to a few* exceptions to open access.  They are open to varying degrees due to restrictions from the data providers (not from RDA.)

To see what is available to you,
  • Click on "dashboard" (at the top of the RDA web portal, right next to "sign out"
  • Then click on "Edit/Change Profile"
  • The bottom half of the screen for an unaffiliated user will look something like this:
Restricted data sets at the RDA.
  • ECMWF Operational data is only accessible to users at UCAR member institutions in the U.S. and Canada, as well as users at all other U.S. universities and government institutions. Eligible users must agree to the ECMWF Terms of Use (TOU).
  • JRA products are available to all affiliated users.
  • COSMIC data access is granted only to affiliated users who have also registered at CDAAC.
  • ECMWF Data (Other Than Operational Data) is available to all registered users who agree to their TOU.
Suppose you want to compare how JRA-55 (ds628.0) and NCEP/NCAR Global Reanalysis (ds090.0) differ over your region of interest.  Read their data set Description pages.  Note that ds628.0 has sections labeled "Access Restrictions" and "Usage Restrictions" while ds090.0 does not.

JRA-55 Access and Usage Restriction information.
Click the "Data Access" tab for JRA-55 and you will see the screen below if you are nonaffiliated. If you are eligible (affiliated), you will be taken to a page with the Terms of Use. Read and accept the Terms of Use and you are then able to access the data.

Nonaffiliated users see this.
If you do have a valid and current affiliation, edit your profile.  Reply to the verification email we send, and then you will be able to read and accept the Terms of Use.
Edit your profile here.  We WILL confirm your email to be sure that it is current.
Some have been reluctant to update their email/affiliations when they leave their universities. Losing access to something you once had is a bummer. I still miss the Olympic-sized swimming pool at Berkeley.

But, users of restricted datasets need to reverify their status by replying to verification email notices sent out every six months. Thus, you don't lose anything by keeping your email and affiliation status up-to-date. In fact, you lose access to email notices that we send out about outages and important updates about data you have downloaded from us in the past.

* Only 78 of our 600+ data sets belong to one of the restricted classes of data sets.
