The application of correlation spectroscopy to the study of dispersion from tall stacks

Vertically-integrated SO2 cross-sections of the plume from a tall stack have been obtained with a dispersive correlation spectrometer. A methodology is described for processing these remotelysensed data to determine plume boundaries, horizontal dispersion coefficients and ground path. In addition, the cross-sections are combined to yield some insight into the diffusion process affecting the plume and this information is used to establish the conditions under which calculations of mass flow can be made.
