On-line coupled meteorology and chemistry models in the US

Abstract

The climate-chemistry-aerosol-cloud-radiation feedbacks are important processes occurring in the atmosphere. 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 review focuses on history and current status of development and application of on-line models in the US Several representative on-line coupled meteorology and chemistry models such as GATOR/GCMOM, WRF/Chem, CAM3, MIRAGE, and Caltech unified GCM are included. Major model features, physical/chemical treatments, as well as typical applications are evaluated with a focus on aerosol microphysics treatments, aerosol feedbacks to planetary boundary layer meteorology, and aerosol-cloud interactions. Recommendations for future development and improvement of on-line coupled models are provided. © 2011 Springer Berlin Heidelberg.
