We have saved CAM-chem simulation output that is intended to be used as boundary conditions for regional modeling. We used CAM-chem in the finite volume dynamical core, at 1 degree global horizontal resolution with XX vertical levels. Meteorology is driven by specified dynamics, by nudging with XXh relaxation (X%) to MERRA2 reanalysis. Data is saved as instantaneous fields every 6 hours. See a list of saved species. Chemistry is calculated using the MOZART-T1 mechanism, described in Emmons et al. (2019). You can find a description of all simulated species in Emmons et al. (2020). We use the MAM4-VBS scheme to model aerosols. Anthropogenic emissions are from CAMS-GLOB-ANTvXYZ. Biogenic emissions are from online MEGAN2.1 modeled interactively via CLM. Fire emissions are from QFED CO2 x FINN emission ratios. SST in 2020 are repeated from 2019.
