China's ozone-forming pollutants drift over California

China's ozone-forming pollutants drift over California

From 2005 to 2010, the western US made huge leaps in cutting ozone-forming pollutants at a 21 percent decrease, but the ozone in the atmosphere did not drop because of a combination of pollutants drifting from China plus a natural uptick in ozone, according to a new study..

NASA's Aura Satellite, Air Quality, and You

The Environmental Protection Agency (EPA) monitors six criteria pollutants to make their air quality forecasts. The Aura spacecraft monitors five of the six pollutants: ozone (O3), carbon monoxide (CO), aerosols, nitrogen dioxide (NO2), and sulfur dioxide (SO2). Scientists use Aura data to monitor the production and transportation of these pollutants across the globe.



NASA Monitors Improving Air Quality in the U.S.

What flies around the world 14 times a day and can detect global air pollution levels from space? It's NASA's Aura satellite, whose mission is to understand the changing chemistry of the Earth's atmosphere. This remarkable satellite can measure air quality across the entire planet in just 24 hours.

Hell with the Lid Taken Off
09.02.2014 - During the first half of the twentieth century, coal burning at power plants, factories, and homes filled the air over the Midwestern U.S. with pollution...

Clearer View of Hazy Skies : Remote Sensing Provides a Global Perspective on Pollution
06.24.14 Industrialization has brought incredible societal advances and difficult pollution problems. From space, we can see skies clearing in some regions and darkening in others. The thin blue line of our atmosphere is still quite vulnerable.

Study of Urban Population and Air Pollution Uncovers Regional Discrepancies
08.20.13 - Through the help of satellite observations, NASA scientists have released the first-ever study to examine just how much more air pollution people living in large cities are exposed to compared to those living in less populous areas.

NASA Ozone Study May Benefit Air Standards, Climate
01.16.13 - A new NASA-led study finds that when it comes to combating global warming caused by emissions of ozone-forming chemicals, location matters.

Sharp Decline in Pollution from U.S. Coal Power Plants
12.01.11 - A team of scientists have used the Ozone Monitoring Instrument (OMI) on NASA's Aura satellite to confirm major reductions in the levels of a key air pollutant generated by coal power plants in the eastern United States. The pollutant, sulfur dioxide, contributes to the formation of acid rain and can cause serious health problems.
