The conclusion is that LIDAR provides a valuable adjunct to standard air quality monitoring and modelling techniques. These LIDAR results provide a unique view of the backscatter height-profiles from coal mine particles passing overhead a vertically-pointing LIDAR. The dust plume was observed to fumigate part of a shallow, wide river valley up to a height of approximately 300 metres above ground level. The source of the dust plume was a dragline machine operating at an open-cut coal mine. This combination of techniques is a novel study of a dust plume observed in the boundary layer. The purpose of this paper is to combine: LIDAR-measured height profiles of (attenuated) laser backscatter from a dust plume Simultaneous ground-level (in situ) measurements of particulate matter and meteorological parameters and Air dispersion modelling, to improve our understanding of the atmospheric dispersion of dust particles.
