Short summary
We use a complete set of simulations to evaluate whether equilibrium and steady state are appropriate for a chemical system involving several reactive nitrogen-containing species (NO2, NO3, and N2O5) under various conditions. A previously neglected bias for the coefficient applied for interpreting their effects is disclosed, and the relevant ambient factors are examined. We therefore provide a good solution to an accurate representation of nighttime chemistry in high-aerosol areas.
