Received: 08 September 2011 – Published in Atmos. Chem. Phys. Discuss.: 20 September 2011 Abstract. Dust storms and associated mineral aerosol transport are driven primarily by
meso- and synoptic-scale atmospheric processes. It is therefore essential
that the dust aerosol process and background atmospheric conditions that
drive dust emissions and atmospheric transport are represented with
sufficiently well-resolved spatial and temporal features. The effects of
airborne dust interactions with the environment determine the mineral
composition of dust particles. The fractions of various minerals in aerosol
are determined by the mineral composition of arid soils; therefore, a
high-resolution specification of the mineral and physical properties of dust
sources is needed.

Several current dust atmospheric models simulate and predict the evolution of
dust concentrations; however, in most cases, these models do not consider the
fractions of minerals in the dust. The accumulated knowledge about the
impacts of the mineral composition in dust on weather and climate processes
emphasizes the importance of including minerals in modeling systems.
Accordingly, in this study, we developed a global dataset consisting of the
mineral composition of the current potentially dust-producing soils. In our
study, we (a) mapped mineral data to a high-resolution 30 s grid, (b)
included several mineral-carrying soil types in dust-productive regions that
were not considered in previous studies, and (c) included phosphorus.
