They found that reductions in ground ozone during this 35-year period resulted in $600 million in increased production annually by the early 2010s. Davis and his colleagues chose to concentrate on perennials because of the long-term investment they represent and the fact that California is a major supplier of this type of produce.

As California continues to reduce local sources of ozone, ozone entering the state from the Pacific makes up a larger fraction of measured ozone levels. An ozonesonde is a balloon which measures ozone from the surface to more than 10 kilometers above the ground.

They found that 6PPD, the primary antioxidant chemical used in tire rubber, reacts with ozone to form the previously unidentified compound 6PPD-quinone. Ozone breaks the bonds holding the tire together. 6PPD reacts with ozone before it can react with the tire rubber, sparing the tires. Davis, Michael C. Scholz, Jay W.
