Imported from Asia: OZONE
January 21, 2010 06:59 AM - Roger Greenway, ENN
Ever wonder how the western US has high ozone levels when the winds usually blow in off the Pacific Ocean? Did you think it was all from the cars clogging the freeways? Turns out, it is caused in part from emissions of ozone generating air emissions from Asia. A study by the National Oceanic and Atmospheric Administration (NOAA) shows that Springtime ozone levels above western North America are rising, primarily due to air flowing eastward from the Pacific Ocean, a trend that is most significant when the air originates in Asia.
