  2. What is GAW? • 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

  3. 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
