The Lineate Imaging Near Ultraviolet Spectrometer (LINUS)1,2 has been used to remotely detect and measure sulfur dioxide (SO2). The sensor was calibrated in the lab, with curves of growth created for the 0.29 - 0.31 μ spectral range of the LINUS sensor. Field observations were made of a coal burning plant in St. John's, Arizona at a range of 537 m. The Salt River Coronado plant stacks were emitting on average about 100 ppm and 200 ppm from the left and right stacks respectively. Analysis of the LINUS data matched those values within twenty percent. Possible uses for this technology include remote verification of industry emissions and detection of unreported SO 2 sources.
