| mip_abstract | The Clouds and the Earth's Radiant Energy System (CERES) project has now produced over two decades of observed data on the Earth’s Energy Imbalance (EEI) and has revealed substantive trends in both the reflected shortwave and outgoing longwave top-of-atmosphere radiation components. Available climate model simulations suggest that these trends are incompatible with purely internal variability, but that the full magnitude and breakdown of the trends are harder to match. Unfortunately, the Coupled Model Intercomparison Project (Phase 6) (CMIP6) protocol only uses observed forcings to 2014 (and Shared Socioeconomic Pathways (SSP) projections thereafter), and furthermore, many of the ‘observed’ drivers have been updated substantially since the CMIP6 inputs were defined. We therefore propose a new, relatively low-cost, model intercomparison, CERESMIP, that would target the CERES period (2000-present), with updated forcings to at least the end of 2021. The focus will be on atmosphere-only simulations, using updated SST, forcings and emissions from 1990-2021. The focus will be on the EEI and atmospheric feedbacks, and so diagnostics would benefit from output from satellite cloud observation simulators. The Tier 1 request would consist of a single AMIP-style simulation, while the Tier 2 request would encompass uncertainties in the applied forcing, atmospheric composition, single and all-but-one forcing responses. |
