Title

The aerosol radiative effects of uncontrolled combustion of domestic waste

Abstract

Open, uncontrolled combustion of domestic waste is a potentially significant source of aerosol; however, this aerosol source is not generally included in many global emissions inventories. To provide a first estimate of the aerosol radiative impacts from domestic-waste combustion, we incorporate the Wiedinmyer et al. (2014) emissions inventory into GEOS-Chem-TOMAS, a global chemical-transport model with online aerosol microphysics. We find domestic-waste combustion increases global-mean black carbon and organic aerosol concentrations by 8 and 6â€¯%, respectively, and by greater than 40â€¯% in some regions. Due to uncertainties regarding aerosol optical properties, we estimate the globally averaged aerosol direct radiative effect to range from âˆ’5 to âˆ’20â€¯mWâ€¯mâˆ’2; however, this range increases from âˆ’40 to +4â€¯mWâ€¯mâˆ’2 when we consider uncertainties in emission mass and size distribution. In some regions with significant waste combustion, such as India and China, the aerosol direct radiative effect may exceed âˆ’0.4â€¯Wâ€¯mâˆ’2. Similarly, we estimate a cloud-albedo aerosol indirect effect of âˆ’13â€¯mWâ€¯mâˆ’2, with a range of âˆ’4 to âˆ’49â€¯mWâ€¯mâˆ’2 due to emission uncertainties. In the regions with significant waste combustion, the cloud-albedo aerosol indirect effect may exceed âˆ’0.4â€¯Wâ€¯mâˆ’2.
