This illustration shows a hypothetical plume and possible series of flight patterns during the PACDEX field project. When a major plume of dust and pollutants begins blowing off Asia, the G-V would fly from Boulder to Anchorage, where it would refuel, and then fly on to Yokota Air Base, Japan. It would then conduct a series of flights for about a week in and around the plume as the plume moves over the ocean to North America. Credit: by Steve Deyo, ©UCAR

Scientists using the nation's newest and most capable aircraft for environmental research are launching a far-reaching field project this month to study plumes of airborne dust and pollutants that originate in Asia and journey to North America. The plumes are among the largest such events on Earth, so great in scope that scientists believe they might affect clouds and weather across thousands of miles while playing a role in global climate.
