Barry Huebert,

Airborne measurements during the 2001 ACE-Asia intensive field operations will contribute to the regional characterization of aerosol properties by providing data from above the surface and downwind of the continent. Aircraft operations will be directed to sample regional aerosol features (e.g. dust outbreaks, urban and industrial plumes) under different synoptic meteorological patterns and at various distances from shore. The goals of these studies are to:
