GEOS-Chem in CESM
Overview
This page contains information and instructions for using GEOS-Chem in the Community Earth System Model (CESM). It is currently in development. - Include citable references here (all CESM-GC papers to date)
CESM Resources
The best way to successfully use GEOS-Chem chemistry in CESM is to become familiar with CESM documentation and guides maintained by NCAR. The CESM2 Quickstart Guide contains an overview of the model and instructions for downloading, building, and running CESM2.
CESM2 is built upon a framework called Common Infrastructure for Modeling the Earth (CIME, pronounced "SEAM") which handles configuring, compiling, testing, and running the model. Offline GEOS-Chem users can think of CIME as run directory management and testing, containing the equivalent of what is found in the 'run' and 'test' directories within GEOS-Chem. Read through the CIME documentation to become familiar with the concepts of CIME and to get detailed instructions for creating run directories, configuring a run, building the source code, and running the model.
Community Atmosphere Model (CAM) is the atmospheric component of CESM and includes both GEOS-Chem and HEMCO as subcomponents. The CAM6.3 documentation builds upon information in the CESM Quickstart Guide and the CIME documentation. Read through it to learn about the atmospheric component's configuration options, data inputs, and model outputs.
