The California Air Resources Board is accepting applications for the 2014 Haagen-Smit Clean Air Awards. Through a series of innovative experiments he demonstrated that most of California’s smog is the result of motor vehicle exhaust and industrial smokestack pollution reacting with sunlight to create ground-level ozone.
