Tropospheric S - C ratios were obtained from international networks such as the NOAA/CMDL Cooperative Flask Sampling Network (National Oceanic and Atmospheric Administration/Cli-mate Monitoring and Diagnostics Laboratory) in cooperation with INSTAAR (Stable Isotope Laboratory at the Institute of Arctic and Alpine Research), the CSIRO network (Commonwealth Scientific and Industrial Research Organization) or the SIO network (Scripps Institution of Oceanography). Within these networks, tropospheric air samples, collected generally in remote areas, are analyzed for [COy] (all sites) and d C ratios (at selected sites Trolier et fl/., 1996).
