A prototype passive infrared sensor for the measurement of sulfur dioxide emissions from stationary sources is described. The infrared radiation emitted by gases in a plume originating from smokestacks may be detected, and from this the SO2 concentration in the plume may be determined. In general, the radiation received by the sensor is a function of the intervening and background atmosphere. Thus, the problem of quantitative measurements is generally complex. A technique is described, based upon the principle of Gas Filter Correlation, which minimizes these effects. This report presents a detailed description of the sensor, its specifications, and performance characteristics. The results of field testing at both oil and coal-burning power plants are compared with extractive sample data. In general, the remote measurements agree with the extractive data within + or - 25 percent over SO2 concentrations ranging from 150ppm to 1300ppm from slant ranges of 130 to 400 m.
