CAM-chem  

Definition

  • The Community Atmosphere Model with Chemistry (CAM-chem) is a component of the NCAR Community Earth System Model (CESM) and is used for simulations of global tropospheric and stratospheric atmospheric composition. CAM-chem uses the MOZART chemical mechanism, with various choices of complexity for tropospheric and stratospheric chemistry. The first version of CAM-chem is described in Lamarque et al. (2012), CAM-chem as used for CCMI and HTAP is described in Tilmes et al. (2016), CAM-chem in CESM1.2 is described in Tilmes et al. (2015). CESM2, including CAM6-chem, is the current version. This version includes a significantly updated tropospheric chemistry mechanism (MOZART-T1) [Emmons et al., 2020], along with a volatility basis set (VBS) parameterization for the formation of secondary organic aerosols (SOA) [Tilmes et al., 2019]. CESM2.0 and CESM2.1 were used for CMIP6 simulations, so if you are interested in simulating results to be consistent with those results it is recommended to use CESM2.1. (en)
