Abstract : EXCEDE III, a rocketborne experiment, made measurements of electron irradiated air over altitudes of 80 to 115 km. High spectral resolution, infrared measurement of the excited air were made with a Michelson type interferometer spectrometer. The recorded data from the interferometer spectrometer require a significant amount of computer processing to convert the data into a useful form and provide spectral intensity as a function of wavenumber. A software package to perform the required computer functions has been developed which permits direct interactive capability. The software has been made very concise and easily fits on a personal computer. The programs may be used to set filter band edges, to preprocess interferograms, co-add any number of interferograms, perform Fourier transforms to recover spectra, allow for rectangular, triangular or Kaiser-Bessel apodization, interpolate the spectral output and generate multiple formatted output. Examples are provided using the EXCEDE III data which illustrate the implementation of the programs. The computer program package has been installed and demonstrated at GL/GPO.
