Wdc/greenhouse gases, tokyo

  • The World Meteorological Organization (WMO) started the Global Atmosphere Watch (GAW) programme in 1989 to improve the provision of systematic and reliable observations of greenhouse gases (CO2, CH4, CFCs, N2O, etc.) and related gases (e.g., CO, NOx, SO2) in the atmosphere. This programme has integrated WMO's monitoring activities under the Global Ozone Observing System (GO3OS) and the Background Air Pollution Monitoring Network (BAPMoN). As one of the important functions of the GAW programme, the World Data Centre for Greenhouse Gases (WDCGG) was established in the Japan Meteorological Agency (JMA) in October 1990 for systematic collection, archiving, and distribution of the data on the concentrations of greenhouse gases and related gases in the atmosphere and the ocean. The WDCGG collects the data on the gases from a number of observation stations around the world involved in not only GAW but also other institutions and research programmes. The collected data are processed into databases, which are then analyzed for concentration levels and trends of the gases on local, regional, and global scales. The results are summarized and distributed as periodical publications to the institutions and individuals submitting the data and to other users.
