Accurately simulating those feedbacks requires fully-coupled meteorology, climate, and chemistry models and presents significant challenges in terms of both scientific understanding and computational demand. This paper 5 reviews the history and current status of development and application of online coupled models. Several representative online coupled meteorology and chemistry models developed in the U.S. such as GATOR-GCMOM, WRF/Chem, CAM3, MIRAGE, and Cal-tech unified GCM are included along with case studies. Major model features, physi-cal/chemical treatments, as well as typical applications are compared with a focus on 10 aerosol microphysics treatments, aerosol feedbacks to planetary boundary layer meteorology , and aerosol-cloud interactions. Recommendations for future development and improvement of online coupled models are provided.
