We have used the GEOS-Chem CO 2 simulation with CO 2 emissions from global monthly-varying fossil fuel use, shipping, aviation and the chemical production of CO 2 from the oxidation

Surface measurements of carbon dioxide mixing ratio from a global network can be combined with atmospheric transport models and a priori estimates of anthropogenic and oceanic

Based on the recent RCP CMIP5 emission scenarios, we then use the model to calculate the present-day and future anthropogenic direct radiative forcing of fine and coarse
