Could satellite measurement of CO help us to better understand sources of atmospheric CO2?
Greater concerns about global warming have resulted in more and more research interest on CO2.
Strong correlations between aircraft measurements of CO2 and CO have been found in East Asia. Moreover, some researchers have used error correlation in the chemical transport model between CO and CO2 to better estimate the surface fluxes of CO2.
Based on the fact that CO and CO2 share some common sources , we believe that it is a good strategy to utilize satellite CO measurement which has relatively high precision to better estimate the contribution of surface emissions to atmospheric CO2 concentration. To provide evidence to do so, we analyze the relationships between surface emission sources datasets (fire and anthropogenic emissions) and satellite measurements of CO and CO2 in three regions with different land types and industry densities.
Expected results would be stronger correlations between anthropogenic emissions between CO concentrations in more industrialized regions, as well as similar seasonal pattern between fire emission datasets and CO concentrations in less-industrialized area.
