Short summary
We develop a new approach to estimate global emission of primary brown carbon from biomass burning and biofuel use and explicitly simulate brown carbon aerosol that has not been considered in climate and air quality models despite of its importance for solar absorption at UV and short visible wavelengths. Using our best simulation results, we estimate radiative effects of brown carbon aerosol for climate and photochemistry.
