CFSv2 is now operational. The CFSRR (Reanalysis and Reforecast of CFSv2) will NOT be extended beyond March 2011. Users must maintain their own continuing archive by downloading the real time operational data from the 7-day rotating archive located at:

The CFS web server is in the process of reconstruction. Data on the server will be unavailable for download until this process is complete. This may take some weeks. Notification will be posted when all the data becomes available. We apologize for the inconvenience.
