Paper Abstract

In this paper, a multiwavelength (355, 532, and 1064 nm) lidar sounding across a stack plume has been computer simulated. The lidar data were then inverted using Klett's iteration method. It is shown that the obtained dust concentration profile is strongly affected by both the strength of the dust emission source and the particle size dispersion. Satisfactory results were only obtained for source strengths below 0.1 g/s. For higher source strengths, (that is more dense plumes) the errors increased rapidly with the increasing plume density. We show that by multiplying the obtained dust concentration profile by a factor dependant on the optical density of the plume satisfactory results can be obtained for source strengths of 1 g/s or higher.
