Campaign Storage

The NCAR Campaign Storage file system is available to the NCAR labs and to universities that have project allocations. It is for the storage of data on publication timescales.

This disk-based file system’s initial storage capacity is 20 PB with plans to increase the capacity each year. It is the preferred alternative to the older, tape-based High Performance Storage System (HPSS).

Data retention policy

Campaign Storage has a five-year retention policy, meaning files will be purged five years after they are copied to the file system. NCAR lab users are expected to collaborate with CISL’s Digital Asset Services Hub (DASH) to develop data migration plans for storage needs that exceed five years.


Each NCAR lab has an allocation of Campaign Storage space and the labs manage how those allocations are used. University users can request Campaign Storage space through the NCAR Resource Allocation System as supplements to their project allocations. Requests must include detailed justification for the amount of space requested.

Transfers and reporting

Users transfer and manage their Campaign Storage files using Globus. The Globus endpoint established for the file space is NCAR Campaign Storage.

How to making transfers using the command line interface is covered in detail here:

The Systems Accounting Manager (SAM) provides overall summary information about the use of allocations. CISL plans to develop additional tools for use in allocation management.
