Short summary
We assessed the sensitivity of simulation accuracy to the duration of chemical and transport operators in a chemistry-transport model. Longer continuous transport operator duration increases concentrations of emitted species. Chemical operator duration twice that of the transport operator duration offers more simulation accuracy per unit computation. The simulation error from coarser spatial resolution generally exceeds that from longer operator duration.
