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. It is also not directly measurable from space due to the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. —Jin et al.

EPA awards $6M in research funding to improve air quality models

Green Car Congress

The US Environmental Protection Agency (EPA) announced $5,959,842 million in research funding to nine institutions to improve air quality models used to simulate ozone, particulate matter (PM), regional haze, air toxics, and emerging pollutants. It will also inform the development of strategies for improving air quality.

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

Although China and India remain the world’s largest consumers of coal, a new University of Maryland-led study found that China’s sulfur dioxide emissions fell by 75% since 2007, while India’s emissions increased by 50%. The results suggest that India is becoming, if it is not already, the world’s top sulfur dioxide emitter.
