Our group simulates mineral dust using WRF/Chem (v.3.1) for Asian region. Several dust emission parameterizations (e.g., Marticorena and Bergametti, 1995; Lu and Shao, 1999; Shao, 2004) were newly implemented into WRF/Chem and model-default soil texture type and vegetation cover data were replaced with soil data from LREIS (Laboratory of Resources and Environment Information System, Chinese Academy of Science) and FAO/UNESCO and vegetation data derived from MODIS fPAR product, respectively. Dust aerosol is treated as a tracer and there is no radiative feedback. We have four size bins for dust: 1.95-2.5, 2.5-5, 5-10, and 10-20 µm.

 

 

 

No emission inventory is needed for dust simulation because the emission amount of dust aerosol is calculated using meteorological information such as friction velocity.
