Abstract: A new data analysis scheme for retrieving Doppler temperatures from high resolution Fabry-Perot spectrometer fringes is described. Important aspects of parametric representation of the instrument function, convolution and the various instrument-broadening functions are discussed in detail. Complete theoretical background highlighting the method for recovering Doppler parameters and involved errors using the instrument-broadened airglow emission profile are provided. Further, a criterion is set to select proper airglow line profiles for the analysis.
