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.
