Аннотация:We present preliminary results of observations of the ozone emission line in winter 2017/2018 by method of microwave radiometry. Measurements of spectra of middle atmosphere ozone were executed with the help of two of mobile ozonemeters (observation frequency 110836.04 MHz). One spectrometer was installed at physical faculty in Peterhof (60N, 30E) in 28 km from the centre of Saint Petersburg 1. Anotherspectrometer was installed at Polar Geophysical Institute in Apatity (67N, 33E). Both devices had identical techniques as measurement and an estimation of vertical structures of ozone. Results of joint ground-based measurements of middle atmosphere ozone content with the use microwave equipment are presented. The importance of similar observations in the studying of the influence of various disturbances on ozone layer is discussed. The comparative analysis of received results with satellite MLS/Aura data, and also with ozonesonde data at station Sodankyla (67N, 27E) and with model profiles is given.
