During the summer of 2004, five satellite-controlled airmass tracking balloons, developed at the University of Massachusetts,
were flown as part of the International Consortium for Atmospheric Research on Transport and Transformations (ICARTT)
campaign. These balloons are notable for their small size (~1 kg mass), unique altitude-control, and long-duration flight
capability. The balloons were embedded in urban plumes from New York and Boston which they tracked over New England, Eastern
Canada and the Atlantic Ocean. Flights ranged from 12 to 120 hours in duration and covered a maximum distance of 3000 km. The
balloons helped guide Lagrangian and semi-Lagrangian aircraft observations of ozone, precursor molecules, and aerosols.
Balloon-based meteorological and, in one flight, ozone observations are analyzed in the context of model trajectories, as
well as aircraft, satellite, and ground station data. The accuracy of the balloons as Lagrangian tracers is accessed,
providing the basis for an improved understanding of regional air pollution.
