Abstract
Atmospheric gaseous pollutants are very numerous in industrial regions. It is estimated that 25 or more pollutant molecules may be found in the atmosphere in significant quantities. The measurement of the concentration of each gas from the complex spectrum obtained by a long-path infrared spectrophotometer requires the fitting of trial spectra composed from a library of spectra. The fitting procedure adjusts the concentrations of the trial spectra until a 'best fit' in a least-squares sense is produced. This report is a description of the physical, mathematical, and calculational principles and procedures for the use of a digital computer program to determine concentrations of atmospheric gases in a path of a few kilometers. Detailed instructions for the computer program and a library of spectra are provided.
