Trends - A Compendium of Data on Global Climate Change

This document provides synopses of frequently used time series of global-change data, particularly records of atmospheric chemistry including carbon dioxide, methane, carbon isotopes, carbon flux, cloud cover, temperature, and ecosystems. 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.
