From the homepage:
Currently making 1.67TB of research data available.
Sharing data is hard. Emails have size limits, and setting up servers is too much work. We’ve designed a distributed system for sharing enormous datasets – for researchers, by researchers. The result is a scalable, secure, and fault-tolerant repository for data, with blazing fast download speeds. Contact us at joecohen@cs.umb.edu.
Some data sets you have probably already seen but perhaps several you have not! Like the crater data set for Mars!
Enjoy!
I first saw this in a tweet by Tony Ojeda.
