CLIVAR's Drought Working Group (DWG) Experiments. 

Runs performed by the CCSM Climate Variability Working Group with 
NCAR's CAM3.5 model at T85 resolution:

Atmospheric model: CAM3.5. 
Land-surface model: CLM3.5.
Ensemble # 1 for all Runs.
1st year of spin-up is not included.
SST forcing provided by the DWG: Fixed anomalous SST patterns superposed
on monthly climatological SST.

Land-surface variables are in the sub-directory /land, inside each
sub-directory.
