Recognizing that expanded and improved observations now make possible a broader assessment of global atmospheric chemistry, the WMO Global Atmosphere Watch programme has published a new report on global and regional trends in reactive gases. This group of gases includes such chemicals as surface ozone, nitrogen oxides, carbon monoxide, sulfur dioxide, and volatile organic compounds, many of which are considered to be harmful pollutants. The first issue of the Reactive Gases Bulletin reviews long-term observation data on volatile organic compounds (VOCs) and discusses past and recent trends....
