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.

This proposal reduces emissions contributing to fine particle (PM 2.5 ) and ozone nonattainment that often travel across state lines. SO 2 and NO x react in the atmosphere to form fine particle pollution and ground-level ozone (smog), which are linked to widespread illnesses and premature deaths. NO x emissions would drop by 52%.

After ten years in orbit, the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite has been in orbit sufficiently long to show that people in major US cities are breathing less nitrogen dioxide. New NASA satellite images released this week demonstrate the reduction of air pollution across the US.
