The long
range transport of dust and anthropogenic aerosols (e.g, black carbon,
organics and sulfates, and air pollution from Eurasia, across
the Pacific Ocean, into North America is one of the most wide spread
and major pollution
events on the planet. This plume passes through the Pacific Ocean
extra
tropical cloud systems, which are important climate regulators through
their large radiative cooling
effect. The effect of this mixed dust-pollution plume on the
Pacific cloud systems and the associated radiative forcing is an
outstanding problem for understanding climate change and has not been
explored. The primary reason is the lack of an airborne platform
that can sample the evolution of this plume in situ all the way across
the Pacific Ocean. The NSF/NCAR G-V research aircraft (G-V) fills
this
observational gap and opens new doors for observing this great
natural/man made phenomenon.
