Short summary
Reactions occur within water in both atmospheric particles and cloud droplets, yet little is known about the organic compounds in cloud water. In this work, cloud water samples were collected at Whiteface Mountain, New York, and analyzed using ultra-high-resolution mass spectrometry to investigate the molecular composition of the dissolved organic compounds. The results focus on changes in cloud water composition with air mass origin – influences of forest, urban, and wildfire emissions.
