Short summary
The temperature and acidity dependence of yields and chemical compositions of the α-pinene ozonolysis SOA were systematically investigated using a newly developed compact chamber system. Increases in SOA yields were observed with the decrease in temperature and under acidic seed conditions. The differences in chemical compositions between acidic and neutral seed conditions were characterized and explained from the viewpoints of acid-catalyzed reactions. Some organosulfates were newly detected.
