ACOM Scientists Take World Tour of ATom-osphere

ACOM scientists Samuel Hall, Lizzy Asher, Kirk Ullman, Eric Apel, Alan Hills, and Becky Hornbrook are currently taking part in the ATom-4 Field Campaign. NASA reports in a press release that the DC-8 research aircraft is sampling "over 400 different gases and a broad range of airborne particles on month-long excursions from Alaska down the Pacific to New Zealand, then over to South America and up the Atlantic to Greenland, and across the Arctic Ocean". These research flights sample air over the world's oceans, where traditional land-based measurements of gases and pollutants cannot operate.
