WMO/GAW was established 1989 by merging GO3OS and BAPMoN. GAW focuses on global networks for GHGs, ozone, UV, aerosols, selected reactive gases, and precipitation chemistry. GAW is a partnership involving contributors from 80 countries. GAW is coordinated by the Environment Division of WMO/AREP. Currently GAW coordinates activities and data from 24 Global stations, 637 Regional stations, and 19 Contributing WMO GAW VOC Workshop 30Jan-1 Feb 2006 2 IGACO Presents the reason and need for Global Atmospheric Chemistry Observations Targets 13 variable groups including reactive gases. Assesses past, current and expected state of observing system for each target variable Reviews requirements for observations for each target variable group Makes 12 General Recommendations and 7 Specific Recommendations Provides a framework for the next generation GAW programme 2008-2015 The IGACO System Components IGACO TARGET VARIABLE LIST Chemical species Air Quality Oxidation Capacity Climate Stratospheric Ozone Depletion O3 H2O (water vapour) CO CO2 CH4 HCHO VOCs N2O NOx = NO+NO2 HNO3 SO2 BrO, ClO, OClO HCl, ClONO2 CH3Br, CF3Br, CFC-11, CFC-12, HCFC-22 aerosol optical properties actinic flux GAW Monitoring Components SCIENTIFIC ADVISORY GROUPS: CAS/WG Environmental Pollution And Atmospheric Chemistry(EPAC) WMO/GAW Secretariat AREP AEROSOL OZONE GHGs PRECIP-CHEM UV REACTIVE GASES QUALITY ASSURANCESCIENCE ACTIVITY CENTRES WCCs, RCCs, Projects Calibration, Training Site Visits, Comparisons CENTRAL CALIBRATION LABORATORIES (World Reference Standard) Twinning Workshops GAW STATIONS & GAWSIS Contributing Networks Global Regional GAW WORLD DATA CENTRES: OZONE/UV GHGs(& Related Gases) AEROSOL PRECIP-CHEM RADIATION Satellite Observations Analysis Synthesis IGACO GAW Target Variable Cal.
