Experiment title 
: 6-year ACCESS-AM3 N96 simulation with climatological aerosol and SST+4K
Summary : Cloud feedback remains the leading source of uncertainty in estimating equilibrium climate sensitivity (ECS). Given large ECS in ACCESS-CM3 and UK models employing the latest UM, it is instrumental to investigate cloud responses to evolving environmental conditions in these models. Here we choose to focus on ACCESS-AM3, the atmospheric component of these model, to elucidate the role of clouds in the model responses to radiative forcing. We have run three 6-year AMIP-style simulations (control, SST+4K, climatological aerosols) from 1982-1987, and this proposal aims to run another simulation with both climatological aerosols and SST+4K. The output variables have been carefully checked in the previous simulations, and this new set of simulation will allow us to investigate model responses to radiative forcings under different present-climate conditions. This is a follow-up to a previous experiment proposal.
Scientific motivation: There are large bias in radiation and clouds in CM2 and ESM1.5. It is important to have a closer examination on individual physical processes using atmospheric only simulations.
