Lidar for continuous monitoring of fugitive dust

摘要

Direct-detection lidar has been demonstrated to be useful in locating probable sources of aerosol pollutants, and to some extent characterizing their density in a qualitative manner. Lidar has been less successful in producing quantitative maps of aerosol pollutants because it does not directly measure the quantity of interest. We describe a CO$-2$/ lidar which has been used to measure airborne coal dust and propose its use in combination with a dispersion model to produce quantitative information.
