A model for the emission of PM 10 dust was developed in 2001 (Draxler et al., 2001) using the concept of a threshold friction velocity which is dependent on surface roughness. Surface roughness in turn was correlated with geomorphology or soil properties for Kuwait, Iraq, part of Syria, Saudi Arabia, the United Arab Emirates and Oman.

The original dust emission algorithm (an option not currently available) was based upon describing the vertical dust flux as a fraction of the horizontal transport: Q = K ρ g-1 U * (U * 2-U *t 2) A where the soil emission factor K and threshold friction velocity U *t varied by soil type and land use. This approach proved to be impractical in
