Climate Models Comparison: CCSM3.0 vs. PetaApps Low Res IE Control

Explore the differences between CCSM3.0 and PetaApps Low Res Interactive Ensemble (IE) models in simulating ocean and atmosphere interactions over 66 years, soon expanding to 150 years. Discover the impact of noise-induced variability on equatorial sea surface temperature anomalies and annual cycles. Engage with interactive ensemble versions, observational estimates, and spectral dynamical core simulations, revealing how coupled feedbacks influence climate dynamics.
