  • OGI has developed rapidly over recent years and has now become one of the leading established technologies for gas leak detection. As a standalone provision, however, OGI functions only to image gas leaks and thus lacks the requisite functionality to interrogate in detail the content and concentration of a gas leak. A greater level of detail is however highly desirable as such information may be used to characterize the source composition, concentration, and emission rate of an identified air contaminant emission plume.
  • some embodiments of the present invention provide an air pollution and emission characterization system and method.
