THE ROLE OF CARBON DIOXIDE IN CLIMATE FORCING OVER THE PAST 26 YEARS
Description: Air samples are
collected through the Climate Monitoring and Diagnostics Laboratory (CMDL) global network, including a cooperative
program for the carbon gases which provides samples from about 100 global clean
air sites, including measurements at 5 degree latitude intervals from three
ship routes. Greenhouse gas concentrations are analyzed in terms of the changes
in radiative forcing during the 26-year period encompassing 1979 through 2004.
The growing fraction of the total radiative forcing due to carbon dioxide is
emphasized and the nature of the interannual variations in the radiative
forcing is explored. The interannual change in total radiative forcing is used
to define an Annual Greenhouse Gas Index (AGGI).
