Paper Abstract

Optimum spectral regions are selected for absorption diagnostics of 38 organic and inorganic atmospheric pollutants in the range of 2.5-4.2 micrometers . Computer code ANLINES is developed and numerical simulation of multicomponent spectra is made. Sounding frequencies for diagnostics of 7 inorganic gases with using first-overtone CO laser and HF/DF lasers are selected. Different parameters of sensitivity and selectivity are discussed: minimum detectable concentrations, partial sensitivities, partial selectivities, cross sensitivities. The comparison of these parameters is made for first-overtone CO and HF/DF lasers.
