Paper Abstract

Passive remote determination of the presence and quantity of gaseous chemicals is of interest for a variety of applications, but has been technically difficult to accomplish because of challenging measurement and analysis difficulties. This paper describes progress in the development of infrared plume analysis software. To unravel the atmosphere, background, and thermal contrast relationships it has been found necessary to obtain both spatial and spectral information and to have a set of codes which take these phenomena into account. Measured data were used along with model analyses to develop advanced plume analysis software (APAS) applicable to calculating how accurately amounts of gas ben be determined from overhead with current and possible future sensor technology. The APAS suite of codes incorporates sensor noise, plume contrast and atmospheric effects modules to arrive at a comparative measure of gas plume detection accuracy. The application of the APAS codes to prediction of detection accuracy for several candidate sensors is shown.
