When the Intergovernmental Panel on Climate Change (IPCC) released its report, one of the questions raised was the role dust mineralogy plays on the atmosphere. The sign of the radiative forcing effect on the climate is poorly understood and is one of the five largest uncertainties in climate models. This work will focus on study of the contribution of dust aerosols to radiative forcing and geochemistry in Earth's system models by developing a new approach to determine the mineralogy of dust source regions from remote sensing data.
