This report is a review of particulate opacity measurement techniques. The relationship between the opacity of plumes and their visual effects, and the relationship between the opacity of plumes and their particulate mass concentration are discussed. The report also discusses optical design characteristics of transmissometers that are necessary for measurement of the opacity of particulate emissions. Various methods for remote measurement of plume opacity are reviewed including the visible emission observer.
