The purpose of this work - further apparatus improvement for measuring of contaminating admixture concentrations in the atmosphere air. The calibration of a CO2-laser trace analyzer of gas impurity in free air on ozone was carried out. The value of differential cross-section of absorption of moleculas of ozone , conforming to lines of radiation of the CO2-laser 9P14 and 9P24 for a case of a broadering of absorptive transitions of moleculas of ozone by air is gauged at atmospheric pressure. The measurements of the ozone content in free air in the central part of Kharkov was carried out by using this value in the term from June 26 till October 26, 1998. It is revealed, that during realization of measurements of average value of concentration of ozone in atmosphere of. Kharkov did not leave for high bound of similar values, reference for large industrial cities a pattern - 2 00 ppb and monotonically descreased with the course of time from 170 ppb in middle summer up to 40 ppb in middle of autumn. Per separate days the measured values of concentration of ozone in atmosphere could differ from average value both in one and in other of the party, but no more, than three times. The outcomes of this SRW will be utilised, unconditionally, hereinafter at the analysis of gas impurity in free air, in business of perfecting of instrumentation for realization of such analysis and have practical concern.
