AUSLEM was developed as a Geographic Information System tool to assess landsusceptibility to w<strong>in</strong>d erosion across western <strong>Queensland</strong>, <strong>Australia</strong>. The model operatesat a 5 x 5 km spatial resolution on a daily time step, us<strong>in</strong>g <strong>in</strong>puts of grass and tree cover,soil moisture, soil texture and surficial stone cover. Model performance was evaluated bycompar<strong>in</strong>g trends <strong>in</strong> the model output with trends <strong>in</strong> w<strong>in</strong>d speeds and observationalrecords of dust events recorded at eight meteorological stations <strong>in</strong> western <strong>Queensland</strong>between 1980 and 1990. The validation was conducted at four spatial length scales, from25 to 150 km. Results show that AUSLEM performs well <strong>in</strong> the arid southern andwestern regions of the study area. Poor model performance at scales
