UCI-led study finds California’s strict air quality regulations have helped farmers

Green Car Congress

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.

CARB, NOAA, NASA and San Jose State University scientists team up to study ozone transported across Pacific

Green Car Congress

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.
