Intercontinental Chemical Transport Experiment - North America Phase A (INTEX-A) is an integrated atmospheric field experiment performed over North America. The study seeks to understand the transport and transformation of gases and aerosols on transcontinental/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. The main constituents of interest are ozone and precursors, aerosols and precursors, and the long-lived greenhouse gases. INTEX-NA is part of a larger international ITCT (Intercontinental Transport and Chemical Transformation) initiative. INTEX-NA goals are greatly facilitated and enhanced by a number of concurrent and coordinated national and international field campaigns and satellite observations. Synthesis of the ensemble of observation from surface, airborne, and space platforms, with the help of a hierarchy of models is an important goal of INTEX-NA.

INTEX-NA is a two phase experiment that aims to understand the transport and transformation of gases and aerosols on transcontinental/intercontinental scales and assess their impact on air quality and climate. The primary constituents of interest are ozone and precursors, aerosols and precursors, and the long-lived greenhouse gases. The first phase (INTEX-A) was completed in the summer of 2004 and the second phase (INTEX-B) is to be performed in the spring of 2006. This document is intended to provide an update on the goals of INTEX-B and define its implementation strategy. The scientific goals envisioned here are based on the joint implementation of INTEX-B, MIRAGE-Mex and DLR/IMPACT studies and their coordination with satellite observations. In collaboration with these partners, the main goals of INTEX-B are to:- Quantify the transpacific transport and evolution of Asian pollution to North America and assess its implications for regional air quality and climate; - Quantify the outflow and evolution of gases and aerosols from the Mexico City Megaplex; - Investigate the transport of Asian and North America pollution to the eastern Atlantic and assess its implications for European air quality; - Validate and refine satellite observations of tropospheric composition; - Map emissions of trace gases and aerosols and relate atmospheric composition to sources and sinks.The INTEX-B field study is to be performed during an approximate 8-week period from March 1 to April 30, 2006.
