CESM2.2 CAM-chem as Boundary Conditions
| DOI: 10.5065/XS0R-QE86
We have saved CAM-chem simulation output that is intended to be used as boundary conditions for regional modeling. We used CAM-chem at 0.9 degree by 1.25 degree horizontal resolution simulation with 32 vertical levels. Temperatures, and winds are adjusted to MERRA2 reanalysis fields with a 12 hour relaxation (10%). Data is saved as instantaneous fields every 6 hours into daily files.
Chemistry is the MOZART-T1 mechanism. Descriptions of all simulated species are available online. We use the MAM4-VBS scheme to model aerosols. Anthropogenic emissions are from CAMS V5.1. Biogenic emissions are from online MEGAN2.1. The fire emissions are from QFED CO2 fields combined with emission factors collated for the FINN inventory to create all the emissions necessary for the CAM-chem simulation. Online ocean DMS emissions are used.
