Cooking is a major source of particles in urban areas. Previous studies demonstrated that the chemical lifetimes of cooking organic aerosols (COAs) were much shorter (~minutes) than the values reported by field observations (~hours). We conducted laboratory experiments to resolve the discrepancy by considering suppressed reactivity under low temperature. The parameterized k2–T relationships and observed surface temperature data were used to estimate the chemical lifetimes of COA particles.
