NSC operates an archive for SMHI that can be accessed with a file system view. This is implemented via the HSM functionality of GPFS (backed by tape) and accessed via SFTP.
Only a limited subset of the data is stored on disk in the archive, but all directories and files are visible as if they were. Data is transparently fetched in the background if it is only available on tape. Vice versa data uploaded to the archive is migrated to tape in the background. The disk storage should be seen more as a cache.
To be able to access Hubble a separate account is needed. It is not the same one as on any other SMHI systems. Please email firstname.lastname@example.org to request one.
Since most of the data is physically located on tape there will be an initial delay when it is fetched from tape. Depending on the amount of data and if it was uploaded at different times it may require mounting several tape volumes. This may lead to variations in how long accesses take. Transferring data in a batch job to a local server is encouraged so it is not dependant on a workstation or a laptop.
