Abstract:
The World Data Centre for Greenhouse Gases (WDCGG) was established at the Japan Meteorological Agency (JMA) in the framework of the World Meteorological Organization (WMO Global Atmosphere Watch (GAW) Program. 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.
WDCGG collects data on concentrations of carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), halocarbons (C-11, CFC-12, CFC-113,HCFC-141b, HCFC-142b,CCl4 , and CH3CCl3), carbon monoxide (CO), nitrogen oxides (NO2, NO, NOx), ozone (O3), and sulfur dioxide (SO2).
The WMO WDCGG Data Summary is one of the WDCGG periodical publications. The Data Summary contains a description of past and current concentrations of gases on the global, regional, and local scales, together with information on observation stations.
The WDCGG acknowledges the support of the organizations and individual researchers in providing data on greenhouse gases. The data are most properly referenced by citing the contributors of the data and the source of the data is also propertly acknowledged. The following citation is presented as an example, choosing a station name appearing first in this issue.
