The objective of this effort was to derive suitable correlation functions for monitoring the atmosphere for specified pollutants by remote ir sensing techniques. The correlation function for a particular target pollutant is calculated by the simplex optimization method. This technique constrains the response of the gas detection system to less than some arbitrary constraint limit for background changes while optimizing system response to the target pollutant. The response to a target pollutant was 2 to 3 times greater than any background induced change over a period of 2 weeks. The technique is applicable to a wide range of spectral analytical problems and may apply to process control as well as remote sensing techniques, particularly in pollution monitoring applications.
