Abstract
The Naval Postgraduate School's Ultraviolet Imaging Spectrometer (NUVIS) is a hyperspectral sensor with a spectral response of 300 to 375 nanometers. This thesis research concentrates on the operation and calibration of NUVIS in the detection of effluent suliur dioxide (SO2) plumes. NUVIS is capable of detecting and quantifying SO2 emissions in the form of effluent smokestack plumes by exploiting SO2's unique Uv absorption signature. Laboratory comparison UV spectra of 502 were recorded and used to calculate curves of growth for four different 502 spectral features. Laboratory results were employed to analyze field data taken of a coal-burning power plant. Analysis of this plume data yielded a mean plume SO2 mixing ratio of 365 i 200 ppm, in agreement with the in situ stack value of 400 ppm. Further assessment of NUVIS indicates that its lower limit for SO2 detection in typical field applications is approximately 70 ppm
