Data Source: EFI EUROFOREST Portal
TitleTrends Online: A Compendium of Data on Global Change
CreatorCarbon Dioxide Information Analysis Center (CDIAC)
DescriptionThis document provides synopses of frequently used time series of global-change data: historical and modern records (from ice cores and current monitoring stations) of atmospheric concentrations of carbon dioxide (CO2); atmospheric concentrations of methane; isotopic measurements (14C et al.) for atmospheric greenhouse gases; estimates of global, regional, and national CO2 emissions from the combustion of fossil fuels, gas flaring, and the production of cement; global emissions estimates for methane (CH4); carbon flux from land-cover change; long-term temperature records, whose spatial coverage ranges from individual sites to the entire globe and from the Earth's surface to the lower stratosphere; total cloud amount over China; ecosystems (area and carbon content). Data records are presented in multipage formats, each dealing with a specific site, region, or emissions species. The data records include tables; graphs; discussions of methods for collecting, measuring, and reporting the data; trends in the data, and references to literature providing further information. Instructions for citing specific data in Trends Online are provided for each compiled data set. All data appearing in Trends Online are available, on request, on digital media from CDIAC at no cost.
