Short summary
Various plant species emit a chemical compound called indole under stressed conditions or during flowering events. Our experiments show that indole can be oxidized in the atmosphere to produce a brownish haze containing well-known indole-derived dyes, such as indigo dye. An airshed model that includes indole chemistry shows that indole aerosol makes a significant contribution to the total aerosol burden and to visibility.
