Impact of aerosol and cloud biases on Southern Ocean carbon and heat uptake in CMIP5 simulations

The Southern Ocean plays a dominant role in the uptake of anthropogenic heat and carbon by the global ocean. We present an assessment of the impact of aerosol and cloud biases on the simulated uptake of heat and carbon by the Southern Ocean using observationally-based metrics. Our analysis focuses on simulations of the modern and future climate submitted to the Program for Climate Model Diagnosis and Intercomparison (PCMDI) as part of the Coupled Model Intercomparison Project 5 (CMIP5) and the Intergovernmental Panel on Climate Change-AR5 (IPCC-AR5) efforts, along with very-high resolution (~8km in the ocean at high latitudes) and ultra-high resolution (~4km at high latitudes) simulations from NOAA's Geophysical Fluid Dynamics Laboratory (NOAA/GFDL).
