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.

Study finds power law scaling relationship between urban population and NO2 pollution

The approximate linear relationship for each region is notable, suggesting that the dependence of urban NO 2 pollution upon population follows a power law scaling with population. Even though larger cities are typically more energy efficient with lower per-capita emissions, more people still translates to more pollution.)
