What is GAW? • WMO/GAW was established 1989 by merging GO 3 OS and BAPMoN, after the signing of the Montreal Protocol in 1987 and establishment of IPCC by WMO and UNEP in 1988.

• GAW focuses on global long­term 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 Atmospheric Environment Research Division (AER) of WMO/RES.

• Currently GAW coordinates activities and data from 24 Global stations, 200 Regional stations, and 19 Contributing stations

Annual Greenhouse Gas Bulletins WMO

Greenhouse Gas Bulletin The State of Greenhouse Gases in the Atmosphere Using Global Observations up to December 2004

Executive summary The latest analysis of data from the WMO­GAW Global Greenhouse Gas Monitoring Network shows that the globally averaged atmospheric carbon dioxide (CO 2 ), methane (CH 4 ), and nitrous oxide (N 2 O) have all reached new highs in 2004 with CO 2 at 377.1 ppm, CH 4 at 1783 ppb, and N 2 O at 318.6 ppb. These value are higher than those in pre­industrial times by 35%, 155%, and 18% respectively. Atmospheric growth rates of these gases are consistent with previous years, though CH 4 growth has slowed during the past decade. The NOAA Annual Greenhouse Gas Index (AGGI) shows that from 1990 to 2004 the total atmospheric radiative forcing by all long­lived greenhouse gases has increased by 20%.

Break out session 1

• Ozone depletion, UV radiation and the Vienna Convention

• Atmospheric chemistry and climate change interaction (including greenhouse gases, aerosols, connection between different scales)

• Globalization of air pollution (including deposition and reactive gases)
