Intercontinental Chemical Transport Experiment - North America

INTEX-NA was an integrated atmospheric field experiment performed over North America during the summer of 2004 that sought to understand the transport and transformation of gases and aerosols on transcontinental/intercontinental scales and their impact on air quality and climate. INTEX-NA flights using the NASA DC-8 were based out of Pease Air National Guard Base in Newington, New Hampshire, and a particular focus in this study was to quantify and characterize the inflow and outflow of pollution over North America. The main constituents of interest were ozone and precursors, aerosols and precursors, and the long-lived greenhouse gases. INTEX-NA was part of a larger international ITCT (Intercontinental Transport and Chemical Transformation) initiative and the scientific goals were greatly facilitated and enhanced by a number of concurrent and coordinated national and international field campaigns and satellite observations.
