Online Trends - A Compendium of Data on Global Change
This website provides access to online databases containing information on atmospheric gases, specific greenhouse gases, and climatic variables. Substances covered in the Atmospheric and Trace Gases section include carbon isotopes, radio nuclides, and aerosols. The Greenhouse Gas section covers carbon dioxide, methane, and carbon-flux. The Climate section contains data on temperature and cloud characteristics. Each category contains a list of reports or data sets, which are focused on that particular topic. Some of the categories contain maps and some allow the user to choose between data spreadsheets or presentations that include consolidated sets of data. This site offers information that dates back into the 1800's and is an excellent resource for quantifying changing atmospheric conditions.
