Objectives:
The Intercontinental Transport and Chemical
Transformation (ITCT) is a coordinated
international research program to address
how the transport of chemicals from one
continent influence the air quality in other
continents, as well as regional and global
climate?. Its foci are:
(i) to investigate intercontinental
transport of manmade pollution, with an
emphasis on ozone, fine particles, and other
chemically active "greenhouse" compounds
(ii) to determine the chemical
transformation that occurs during this
transport.
There is increasing evidence that ozone and
fine particles and their precursors, even
compounds with reasonably short lifetimes,
can be detected at great distances from
their sources. The "intercontinental" nature
of manmade chemical pollution has been
demonstrated in studies over the last
decade. ITCT will further the scientific
understanding of the consequences - both for
air quality and for climate - of this
intercontinental transport and
transformation. Investigations will
initially focus on the Northern Hemisphere,
which contains most of the world's
landmasses and population, and where most
anthropogenic pollution originates.
ITCT is a newly initiated activity of the
International Global Atmospheric Chemistry
(IGAC) program, which is a Core Project of
the International Geosphere-Biosphere
Programme (IGBP). ITCT combines two earlier
IGAC activities: the North Atlantic Regional
Experiment (NARE) and the East Asian/North
Pacific Regional Experiment (APARE). While
the bulk of the ground studies will be
conducted at Trinidad Head in Northern
California, additional sites are needed to
fully understand the context of long-range
pollution transport at the intensive site.
Therefore, additional sampling sites are
proposed to better characterize the extent
and nature of long-range pollution transport
events. Crater Lake NP is one such site
proposed for this experiment.
Crater Lake is an excellent site to observe
transport across the northern Pacific. It
sits atop the Cascade crest with an
unobstructed fetch to the Pacific,
experiences consistent westerly winds, and
the local area is heavily forested, reducing
the likelihood of any persistent local dust
source. Furthermore, there are few urban or
industrial emission sources in the lowlands
separating it from the Pacific. Sitting at
an elevation of 3078 meters, Crater Lake is
well above the persistent surface inversion
over the eastern Pacific, and is in the
heart of the mid-troposphere "transport
layer" in which aerosols are easily carried
very long distances. Asian dust has been
detected at Crater Lake, most notably in the
great "Yellow Sand" event of April 1998, and
statistical analysis of the entire IMPROVE
record there suggests that Asian transport
to Crater Lake is common from February to
November. In order to set-up a 3- or 8- DRUM
sampler at Crater Lake, we need an outlet
for power and a place to set-up the sampler
with outside air. The air intake for the
sampler would be piped into an existing air
intake in the Ratt Hall attic.
