Abstract

The RELIP (Retrieving Line Parameters) software for photo- acoustic (PA)-spectroscopy data processing is developed in the Laboratory of Atmospheric Absorption Spectroscopy of the Institute of Atmospheric Optics SB RAS. This software is developed for reconstruction of line centers and halfwidths from experimental absorption spectra. The well-known line contours such as Doppler, Voigt, and Lorentz shapes are used in the fitting procedure. It is possible to reconstruct simultaneously the above-mentioned parameters for several absorption lines. The experimental data of a special form such as frequency derivative of the PA signal are acceptable. There is an additional option aimed to compensate for the background of a signal. The software provides the graphical presentation of the measurement data and fitting results together with the tables. There are many options simplifying processing of experimental and model data using this software. The experimental data on the PA signal and the PA signal derivative for the absorption bands of H₂O lying near 0.69 micrometers and 0.59 micrometers as well as the model calculations are used at the software testing.
