ABSTRACT:
This invention is method and apparatus for measuring, at a remote location, the concentration and velocity of SO.sub.2 in plume from a smokestack. An ultraviolet video system views the plume against the background sky at wavelengths where SO.sub.2 molecules absorb light. The result is a real time display of the plume coupled with means for measuring the SO.sub.2 concentration at any point in the plume and at any time desired. In addition, means are provided in combination with the ultraviolet video system for measuring the velocity of the SO.sub.2 in the plume.
