AB: In previous work we constrained the refractive index of Saharan dust aerosols by combining the results of a three-dimensional aerosol microphysics, transport, and radiation model with EP-TOMS radiance measurements and aerosol index. Here we extend this technique in an investigation of biomass burning aerosols over the southern Atlantic Ocean during the SAFARI-2000 experiment. Our aerosol model treats the transport, evolution, and radiative properties of dust, sea salt, and biomass burning aerosols. We compare the computed aerosol optical properties to measurements made with EP-TOMS, MODIS, and MISR in an effort to constrain the radiative and microphysical properties of the relevant aerosols. This effort will lead to better estimates of the aerosol direct radiative effect.
