Popis:	The possibility of remote detection of SO2 in the 9-μm region of the spectrum by means of a TEA CO2 laser was theoretically and experimentally investigated with regard to the real state of the atmosphere and the contribution of background concentrations of H2O, CO2 and NH3 to absorption. For sounding along short paths (2L=2 km), the method of detection of small concentrations of SO2 (at the MPC level) with the use of the lines of the CO2-molecule regular transitions (00o1–02o0 band) has been devised and experimentally tested. It is shown that in sounding along longer paths (2L=6 km), a noticeable increase in sensitivity can be achieved by the generation lines of the CO2-molecule sequential 00o2–02o1 band.
