Springtime ozone distributions for 1984, 1995–2008 in the mid-troposphere (3.0–8.0 Springtime ozone levels above western North America are rising primarily due to air flowing eastward from the Pacific Ocean, a trend that is largest when the air originates in Asia. The US EPA recently proposed new tougher ground-level ozone standards.
