Secondary organic aerosol
ID: secondary-organic-aerosol
Secondary organic aerosol (SOA) refers to fine particles (aerosols) that form in the atmosphere from the gas-phase oxidation of organic compounds. These organic compounds, which can originate from both anthropogenic (human-made) and biogenic (natural) sources, undergo chemical reactions when they react with oxidizing agents, such as hydroxyl radicals (•OH) or ozone (O3).
