Due to unforeseen technical issues, the launch of the Restricted-use Data Analysis System (RDAS) will occur later than anticipated. It is planned for release by fall 2017.
The earliest the Data Portal (which will have more restricted-use datasets) is expected to be available to previously-approved users is fall 2017. Once users who already had access and those who had approval, but had not been granted prior access are successfully onboarded, a call for new applicants will go out. An open call for Data Portal applications will likely be released in late 2018. We do not have an exact date.
