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.

New methods of testing and simulating air quality should be considered in order to help policy makers have a more accurate understanding of how emissions affect air pollution levels, new research suggests. The researchers compared current techniques used to describe atmospheric chemical reactions against more historical techniques.

Bromine then reacts with a gaseous form of mercury, turning it into a pollutant that falls to Earth’s surface. Bromine also can remove ozone from the lowest layer of the atmosphere, the troposphere. Despite ozone’s beneficial role blocking harmful radiation in the stratosphere, ground-level ozone is a harmful pollutant.

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below.

There is an exception to that in the category of what they call super pollutants, the very powerful but shorter-lived gases and chemicals that come from things like fertilizer production, methane. So those are really important, and those are a little bit different. And that was based on observations of volcanoes. They also mix with clouds.
