Short summary
Ambient ion chemical composition measurements provide insight into trace gases that are precursors for the formation and growth of new aerosol particles. We use a new data analysis approach to increase the chemical information from these measurements. We analyze results from an agricultural region, a little studied land use type that is ~41 % of global land use, and find that the composition of gases important for aerosol formation and growth differs significantly from that in other ecosystems.
