چکیده
Indole is emitted from the biosphere by plants under stressed conditions. The SOA yield of Indole was measured in a smog chamber. The particles were collected and the mass absorption coefficient determined at various wavelengths. With nanospray desorption electrospray high resolution mass spectrometry and DART-MS the molecular formula of a series of species in the aerosol phase was identified and attributed to possible compounds. Some of these were confirmed by their UV spectra with HPLCPDA-HRMS. Since many of the products determined absorb in the UV, the authors hypothesize, that indole SOA may considerably contribute to brown carbon. They investigate this with the help of an airshed model, which they updated with some new indole oxidation reactions. They conclude that indole SOA can considerably contribute to decreased visibility and poor air quality in rural and agricultural areas. The paper is well presented. The experimental work is well done and adds new information to a

Interactive comment on “Secondary Organic Aerosol from Atmospheric Photooxidation of Indole” by Julia Montoya et al
The paper reports secondary organic aerosol (SOA) yield, mass absorption coefficient (MAC) values, and light-absorbing compounds in SOA produced from photooxidation of indole. High SOA yield was observed and several compounds (i.e. -heterocyclics) were found to absorb visible light. Additionally, an air quality simulation was used to evaluate the contribution of indole-SOA to total atmospheric ...

This manuscript describes a laboratory study on the photo-oxidation of indole under low-NOx conditions. Secondary organic aerosols (SOA) were chemically characterize to determine the importance of indole chemistry in the formation of brown carbon (BrC) constituents. State of art analytical techniques (high-resolution mass spectrometers) used is this study, provide novel and important insights i...
