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
ICARTT: THE PLAYERS DLR, CNRS NOAA/ ITCT NASA/ INTEX UK/ITOP COBRA MSC Zoom over northeastern North America NEAQS Caltech/ ONR DOE/ASP
(July 2000) CO from MOPITT, AIRS SATELLITE NEAR-REAL-TIME DATA DURING ICARTT AODs (and fires) from MODIS AOD (July 2000) HCHO, NO2 from GOME NO2 from SCIAMACHY GOME HCHO (July 1996) Monthly means from previous years
WCB OUTFLOW EVENT ON JULY 2-5, 2000observed by MOPITT and MODIS-Terra, and simulated with GEOS-CHEM MOPITT, Jul 2-3 MODIS, Jul 3 MODIS, Jul 5 Li et al., 2004
ICARTT objectives ICARTT COORDINATION IN THE FIELD Obtain a seamless data set across platforms optimized to 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)
TRANSATLANTIC LAGRANGIAN EXPERIMENTwill require coordination of NOAA, NASA, UK, DLR aircraft
AEROSOL RADIATIVE CLOSURE EXPERIMENTS integrate aircraft, satellite, ground-based lidar data Direct effect Indirect effect
