Abstract

The dialog package SAGDAM (sounding of atmospheric gases by differential absorption method) is intended for simulation of the potentialities of the DAS method for sounding water vapor and ozone on the vertical and slant directions with ground-based, airborne, and spaceborne lidars. Moreover, the package enables one to model the ground-based, airborne, and spaceborne systems for sounding the integral gas content by a long-path differential absorption method. The spectral range is near UV, visible, and infrared spectral ranges. The program calculates: a) vertical profiles of the absorption coefficients and transmittance of the gas under study and the foreign gases, as well as the transmittance of aerosol and Rayleigh atmosphere; b) spatially resolute error including random error and systematic error. The program enables one to determine the optimal pairs of wavelengths for sounding a gas in the specified altitude range and the minimum-detectable concentration of the gas under study (for the long-path method).
