Caltech researchers are investigating air quality in the South Coast Air Basin, focusing on understanding the impact of a special type of chemicals called volatile chemical products. They are using field measurements, lab experiments, and computer models to analyze data collected during a 2021 research campaign. By identifying and studying these chemicals, they aim to grasp their effects on air pollution and contribute to cleaner air in California.
