The Intercontinental Chemical Transport Experiment (INTEX-B) is the second phase of a two-part, multinational monitoring project designed to track pollution making its way into North America and is sponsored by the Tropospheric Chemistry Program at NASA headquarters. Using information gathered from the ground, aircraft, and satellites, NASA and project partners the National Science Foundation and the U.S. Department of Energy plan to study the chemistry and properties of carbon monoxide (CO) and aerosol emissions originating in Asia and Mexico City. Atmospheric chemist Hanwant Singh is INTEX-B's lead mission scientist.
