1 DIURNAL OCEAN-ATMOSPHERE COUPLING
Danabasoglu, Large, Tribbia, Gent, Briegleb, and McWilliams Evaluate the standard air-sea coupling implemented in CCSM3 Document the changes in the ocean model since CCSM2 CCSM3 (T85x1) Levitus / Rest C1D Levitus / Rest NO DIURNAL CYCLE C3H y50 of CCSM C1H y50 of CCSM
