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
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
