Researchers tap rare pristine air to reveal pollution's impact

(DOE/Pacific Northwest National Laboratory) Human-caused pollution spurs the production of climate-changing particles known as secondary organic aerosols much more than previously thought. Researchers made the finding by analyzing air samples that were captured aboard a research aircraft as it zigzagged between pristine air over the Amazon rainforest and polluted air over the nearby city of Manaus. It was like a trip back (and forth) through time, as scientists weaved between the two vastly different settings.
