Now the science of what's in our air - how to figure out what's polluting it. Capturing what comes out of the tailpipe or power plant is fairly straightforward. It gets more complicated with oil and gas fields. Well, this month, scientists from the National Oceanic and Atmospheric Administration or NOAA are flying an airborne research lab over states with these fields. Mose Buchele sent this report from member station KUT in Austin.
MOSE BUCHELE, BYLINE: The researchers are looking at the big picture, flying over America's sprawling shale fields. Those are the places where fracking created a boom in oil and gas drilling. The project tracks things like ozone and methane emissions.
