Estimates of springtime soot and sulfur fluxes entering the Arctic troposphere: Implications to source regions

Abstract A box model calculation is used to make preliminary estimates of the springtime fluxes of carbon and sulfur particles into the Arctic troposphere. These fluxes are large and can only be accounted for by major sulfur and soot sources. Comparison of these fluxes with the amount of fuel burned in various latitude bands indicates that the Arctic haze cannot be due to Arctic sources and strongly suggests that the dominant source regions are below 60°N latitude. Comparisons of Arctic sulfur fluxes with sulfur emissions on a regional and global basis indicate that significant fractions enter the Arctic.
