Caption: Times italic, Size 9 pt.
GOAL: To understand the impacts ofintercontinental pollution transport on airquality and climate from local to global scales
PARTNERS: United States (NASA, NSF,DOE), Mexico, Canada, and Germany
MISSION: INTEX-B/Milagro was a highlysuccessful international campaign led byscientists from ARC (H. Singh, Lead MissionScientist) with over 300 participants. Thecampaign was performed in the spring of 2006in two parts: the first part (March) investigatedpollution export from Mexico City and thesecond part (April-May) focused on thepollution export from Asia to North America.Multiple satellites, instrumented aircraft,ground stations, and models were utilized toachieve mission objectives.

SCIENTIFIC OBJECTIVES:
• Continental Outflow: Extent & persistence of theoutflow of pollution from Mexico
• Transpacific Pollution: Transport and evolution ofAsian pollution & implications for air quality &climate
• Air Quality: Relating atmospheric composition tosources & sinks & testing chemical transport models
• Aerosol Radiative Forcing: Characterizing effectsof aerosols on solar radiation
• Satellite Validation: Validating space-borne observations of tropospheric composition
PRESENT STATUS:
INTEX-B/Milagro has provided a comprehensive andunique data set for investigating the transformation ofgases and aerosols during long-range transport, for theradiation balance of the troposphere, and for validating avariety of satellite observations as well as models ofchemistry and transport. These data are presently beinganalyzed and will be published in a series of papers inpeer reviewed journals.
