INTEX-A Data Sets

 

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.
