OZONE MEASUREMENTS AT MILLIMETER WAVES USING ATMOSPHERIC CALIBRATION
The article presents the results of studies of the radiophysical observatory named after professor T.Orozobakov on frequency detuning during atmospheric calibrations. Radiophysical measurements of the features of the middle atmosphere, followed by the determination of temporal variations in the concentration of stratospheric ozone over the region of Central Asia are presented in brief. The research method consisted in passive sounding from the Earth's surface of the thermal radio emission of atmospheric ozone molecules in the vicinity of one of the lines of the rotational spectrum of this gas, the resonant frequency of which is close to 110836 MHz. The results of a series of episodic microwave measurements of the altitude distribution of ozone and experiments on atmospheric calibration are presented. So far, at the «zenith», ozone concentrations are significantly inferior to data on reference loads. By absolute calibration, as in previous years, the results of observations correspond to the distribution of ozone over the region of ground-based measurements of the observatory.
