dc.description.abstract Using a Fourier transform infrared field spectrometer, spectral infrared radiance measurements were made of several generated gas plumes against both a uniform sky and terrestrial background. Background temperature, spectral complexity, and physical homogeneity each influenced the success of emissive infrared spectral sensing technology in detecting and identifying the presence of a gas plume and its component constituents. As expected, high temperature contrast and uniform backgrounds provided the best conditions for detectability and diagnostic identification. This report will summarize some of SITAC’s findings concerning plume detectability, including the importance of plume cooling, plumes in emission and absorption, the effects of optical thickness, and the effects of condensing plumes on gas detection. en_US
dc.description.sponsorship The authors would like to thank the Central MASINT Organization, its Technology Coordination Office, SITAC, Los Alamos National Laboratory, and the Environmental Protection Agency (EPA) Region-7 for the sponsoring and support of these collections. These efforts particularly benefited from the efforts and dedication of Mark Thomas of the EPA, participants from AeroSurvey, LANL, Airborne Imaging, McKinzie Environmental, Rochester Institute of Technology, and ABB Bomem. Craig Miller and Joe Leckie from SITAC provided able assistance with the experimental setup and measurements. en_US
