The GFDL Global Atmospheric Chemistry-Climate Model AM4.1: Model Description and Simulation Characteristics

Wednesday, Dec 16, 2020

The atmospheric model documented in this study, AM4.1, marks the culmination of GFDL’s 4th-generation model development effort that included comprehensive revisions of atmospheric dynamics, physics, and chemistry, and biogeochemical coupling to land and ocean. These efforts were merged into a single atmospheric configuration in support of NOAA’s first coupled carbon-chemistry-climate Earth system model (ESM4.1) with state-of-the-art representation of each component, along with comprehensive interactions between components. The study, published in JAMES, was led by AOS Faculty Member Larry Horowitz, a physical scientist at GFDL, with GFDL and AOS/CIMES researchers among the paper's co-authors.
