| Popis: | We consider the instrumentation and methods for the nighttime ground-based measurements of the atmospheric-ozone emission line at a frequency of 142.175 GHz. The ozone-radiation spectra were measured in Moscow in the 2014–2016 cold months with a time resolution of about 2 min. We performed a frequency-time analysis of variations in the differences of the brightness temperatures of the ozone-emission line for the frequency offsets 0–50, 50–150, and 150–250 kHz from the line center. Variations with periods from 6 min to 3 h, which can be related to the wave propagation in the mesosphere and the lower thermosphere, were revealed using the data windows with halfwidths of 10–60 min. |
