Interests in a long and short term variation of tropospheric ozone has increased intensively since its possible importance as a greenhouse gas has been recognized. Synergistic adverse effect of surface ozone on vegetation together with acid deposition is another serious environmental concern. The objective of this project is to compile distribution and seasonal variation of surface ozone with regional representativeness in the world. The output will provide a global picture of regional ozone and would be useful for testing of models. WMO/GAW stations provide surface ozone data with well qualified regional representativeness. The density of the station is not necessary high enough to cover the most important part of the world. This Commission of IUPAC is a suitable body to compile more intensive data taken at a national level, which fill gaps between WMO stations.
