DUST (PM10, 2.5) entrainment from natural soils is a major contributor to
air pollution from particulates, especailly in arid and sparsely vegetated areas.
Dust due to wind erosion can exceed pyrogenic sources by far. AirWare includes a dynamic DUST model
that uses a range of spatial data sets (DEM, soils, dynamic vegetation index) together
with model generated soil moisture and wind speeds. For the erosion estimates,
average hourly wind speeds (generated by MM5 at a 3 km resolution, then diagnostically interpolated to 1 km)
Are extended (using a Weibull distribution) into a frequency distribution of wind speed within that hour,
driving a highly non-linear (exponential) threshold model of wind erosion.
These erosion estimates are then fed, together with all pyrogenic erosion data,
into the CAMx fate and transport model, running for a set of nested model domains to
combine long-range transport under rare but extreme conditions with the more continuous local effects.
