1. ICARTT: COORDINATED ATMOSPHERIC CHEMISTRY CAMPAIGN OVER EASTERN NORTH AMERICA AND NORTH ATLANTIC IN SUMMER 2004
International,
multi-agency
collaboration
SCIENTIFIC OBJECTIVES
Regional Air Quality: characterize sources and transport of pollution in northeastern North America
Continental Outflow: quantify North American outflow of environmentally important gases and aerosols, relate to sources
Transatlantic Pollution: understand transport and chemical evolution of North American pollution across the Atlantic
Aerosol Radiative Forcing: characterize direct/indirect effects of aerosols over northeastern North America and western North Atlantic

5. ICARTT COORDINATION IN THE FIELD
Obtain a seamless data set across platforms optimized to ICARTT objectives
ICARTT
objectives
THIS WILL REQUIRE:
Forecast sharing (web posting)
Data sharing (quick release, web posting, consistent formats)
Aircraft intercomparisons
Surface station overflights
Satellite validation (AIRS, MOPITT, GOME, SCIAMACHY, MODIS, TES, OMI)

6. TRANSATLANTIC LAGRANGIAN EXPERIMENT will require coordination of NOAA, NASA, UK, DLR aircraft

7. AEROSOL RADIATIVE CLOSURE EXPERIMENTS integrate aircraft, satellite, ground-based lidar data
Direct effect
Indirect effect
