The World Data Centre for Greenhouse Gases (WDCGG) was established at the Japan Meteorological Agency (JMA) in October 1990 to make collection and distribution of data on the concentrations of greenhouse and related gases (CO2, CH4, CFCs, N2O, O3, CO, NOX, SO2, VOC, etc.) in the atmosphere and the ocean. The WDCGG collects data from the GAW observing network, research organizations, and other cooperative programmes. As of February 2003, 258 stations in 59 countries (the most recent statistics) have contributed observational data for greenhouse and related gases to the WDCGG.
The WDCGG makes periodical publication of "WDCGG Data Report", "WDCGG CD-ROM", "WDCGG Data Catalogue" and "WDCGG Data Summary". The "Data Report" presents monthly and annual means and the "CD-ROM" contains hourly, daily, monthly and annual means of concentrations of greenhouse and related gases. Also recorded is information on contact persons, methods of measurement and calibration at the observation stations. The "Data Catalogue" provides an index of existing data along with procedures for data access. It also includes information on site environment, measurement procedures, and calibration techniques. The "Data Summary" is designed to describe analytical results on the past and present conditions of gas concentrations on local, regional, and global scales. These publications are distributed on a regular basis to the Permanent Representatives of the WMO Members, data contributors, and other relevant organizations and individual researchers. They are also offered free of charge upon r
equest if the data are used for non-profitable purposes.
