Abstract

We developed a high-sensitivity receiving and measuring facility designed for observations of the ozone O3 and carbon monoxide CO spectral lines by the method of ground-based remote sensing of the atmosphere in the 90–116 GHz frequency range. The measurement and calibration procedure is described in detail. The results of observations of the O3 and CO emission lines at frequencies 110.836 amd 115.271 GHz, respectively, are presented. The sensitivity level of the receiving and measuring facility, which was implemented in the experiment using a filter-bank analyzer and a Fourier spectrum analyzer is determined.
