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.
