Short summary
Atmospheric aerosols affect human health and climate change, yet understanding their formation remains challenging. We studied oxygenated organic molecules, key intermediates, in a complex urban environment in China. Using an advanced analytical method, we identified major chemical pathways and how environmental factors influence them. Our findings enhance the understanding of atmospheric chemistry, offering insights for better environmental and climate policies.
