Short summary
Monocarboxylic acids (MCAs) in gases and particles were measured in deciduous forest. Formic acid in the gas phase and isopentanoic acid in the particle phase were dominant MCAs. Gaseous normal monoacids showed positive correlations with isobutyric acid. Particulate isopentanoic acid showed a positive correlation with lactic acid. The florest floor with soil microbes contributes to emission of MCAs. Our results may be useful to improve understanding of organic aerosol formation in the forest.
