Short summary

Aerosols and the ground provide two kinds of surfaces for multiphase reactions in the planetary boundary layer. However, the relative importance of these two surfaces for gas uptake has not been quantified. We compare the uptake fluxes of aerosols and the ground surface for reactive trace gases under various conditions. More studies regarding O₃ uptake on liquid organic aerosols and H₂O₂ uptakes on various aerosols are needed considering their potential important roles in atmospheric chemistry.
