The Intercontinental Chemical Transport Experiment (INTEX-NA) is a major NASA
science campaign to understand the transport and transformation of gases and aerosols
on transcontinental and intercontinental scales and their impact on air quality
and climate. A particular focus in this study is to quantify and characterize
the inflow and outflow of pollution over North America. INTEX will also provide
important validation of satellite observations with ongoing satellite measurement
programs, such as Terra, Aura, and Envisat. The experiment will be conducted over
the continental United States during the summer of 2004 using a variety of science
aircraft. Several coastal and continental sites across North America have been
selected as bases of operation. The experiment will be supported by forecasts
from meteorological and chemical models, surface and satellite observations, and
ozone probe releases.
The
INTEX-NA campaign will be greatly facilitated and enhanced by a number of concurrent
national and international field campaigns. The National Oceanic and Atmospheric
Administration (NOAA) is the principal U.S. partner for NASA and will field coordinated
airborne and shipboard platforms. Plans are also underway for the United Kingdom,
Germany, Canada, and France to conduct concurrent airborne campaigns to measure
the transport of pollution from North America into the eastern Atlantic and to
Europe. Synthesis of the combined observations from surface, airborne, and space
platforms will maximize scientific results and should directly benefit scientific
understanding of air quality and its relation to climate change.
