Short summary

We simulate atmospheric ²²²Rn using the GEOS-Chem model to improve understanding of ²²²Rn emissions and characterize convective transport in the model. We demonstrate the potential of a customized global ²²²Rn emission scenario to improve simulated surface ²²²Rn concentrations and seasonality. We assess convective transport using observed ²²²Rn vertical profiles. Results have important implications for using chemical transport models to interpret the transport of trace gases and aerosols.
