Intercontinental Chemical Transport Experiment - North America Phase A
(INTEX-A) is an integrated atmospheric field experiment performed over
North America. It 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 longlived greenhouse gases.
