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

Green Car Congress

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.)

UMD-led study finds China’s SO2 emissions down 75% since 2007, India’s up 50%; India may now be the top SO2 emitter

Green Car Congress

Sulfur dioxide is an air pollutant that causes acid rain, haze and many health-related problems. Most of the two countries’ sulfur dioxide emissions come from coal-fired power plants and coal-burning factories. The country opened its largest coal-fired power plant in 2012 and has yet to implement emission controls like China.

NASA satellite images highlight US air quality improvement with reduction of NO2

Green Car Congress

New NASA satellite images released this week demonstrate the reduction of air pollution across the US. 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.

Satellite method provides insight into ozone-NOx-VOCs sensitivity for different locations

Green Car Congress

Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. Determining effective strategies for mitigating surface ozone (O 3 ) pollution requires knowledge of the relative ambient concentrations of its precursors, NO x , and VOCs.
