The Intercontinental Transport and Chemical Transformation (ITCT) project is a major research activity of the International Global Atmospheric Chemistry (IGAC) program that directly addresses the tropospheric chemistry and transport of ozone, fine particles and other chemically active greenhouse-compounds. This activity is aimed at understanding the long-range transport of ozone and aerosols and the impact that this intercontinental transport has on regional climate and air-quality.
About 150 Scientists from 33 government, university, and industry laboratories participated in the ITCT 2002 project from April - May of 2002.
Field Sites and Related Studies
The ITCT 2002 project consisted of aircraft research flights aboard the NOAA WP-3D, extensive ground-based measurements at Trinidad Head, California, and collaborated efforts with two other research projects, PHOBEA and PEACE.
Modeling and Forecasts
As well as in situ measurements, a major component of the ITCT 2002 project was the forecasting and modeling of long range transport. Meteorological and satellite data feeds (GOES-West and GMS5 geostationary infrared and water vapor) and a variety of 3D chemical transport models from regional to hemisphere to global scale were run to facilitate the flight planning. Forecasting activities included two three-dimensional tracer models used to forecast long-range transport and transformation of ozone and aerosols, their precursors and other trace chemicals, and particle dispersion models incorporating forecast wind fields which transport and disperse a passive tracer available daily.
