On the MARVEL website, the dataset index lists all published datasets resulting from NCCR MARVEL research. It is updated every year, in February.
Regarding data storage and backup during research, MARVEL offers central storage for computational members at CSCS on "/store". Local storage within the institutions and the research groups is also possible, keeping in mind the importance of backups and backup retention. MARVEL requests at least weekly backups. It recommends a three-month backup retention, but accepts as a minimum a one-month backup retention. The EPFL Library reminds us of the horror of lost data in a humorous story.
