| mip_abstract | Phase 2 of the Aerosol Chemistry Model Intercomparison Project (AerChemMIP2) focuses on the quantification of the climate, atmospheric composition, and air quality responses to changes in emissions of aerosols and chemically reactive gases. Such short-lived climate forcers (SLCFs) play a fundamental role in regional and global climate change. AerChemMIP2 aims at a better understanding of the relative contributions of individual SLCF emissions to composition change, radiative forcing, and the climate response from the pre-industrial to present-day as well as for projected future emission scenarios. Assessing feedbacks from natural emissions relevant to SLCFs on atmospheric composition and climate change is a key component in AerChemMIP2. The experimental protocol builds on methodological knowledge, e.g., gained through AerChemMIP, RFMIP, and ScenarioMIP, which were endorsed by CMIP6. Specifically, AerChemMIP2 seeks to closely align with the CMIP7 core experimental design, namely the Diagnostic, Evaluation and Characterization of Klima (DECK), historical, and future scenario experiments. The design of the AerChemMIP2 ensemble of experiments will be informed by results from emulation techniques for an optimal tradeoff considering the ensemble size, resolution, and length of the experiments as well as scientific goals, in light of limited computing resources. In addition to the proposal of new Earth system model experiments, AerChemMIP2 requests diagnostic output from CMIP7 core experiments to facilitate targeted analyses on the role of aerosols and chemistry in composition and climate change. This can include output from kilometer-scale climate experiments through the advancement of the next generation of global coupled atmosphere-ocean models. In so doing, AerChemMIP2 strives to generate policy-relevant information on modern climate change, contributing new knowledge and estimates on the role of individual SLCFs. |
