Description :
AUSLEM is distinctive in that it quantitatively assesses landscape susceptibility to wind erosion at a 5x5 km spatial resolution on a monthly time-step across Australia. The system was implemented for representative wet (1984), dry (1994), and average rainfall (1997) years with corresponding low, high and moderate dust storm day frequencies. results demonstrate that AUSLEM can identify landscape mobility, and provide an interpretation of the physical nature and distribution of erodible landscapes in Australia. Further, results offer an assessment of the dynamic tendencies of erodibility in space and time in response to the El Niño Southern Oscillation (ENSO) and seasonal synoptic scale climate variability.
