We present data continuous series of microwave observations of the middle atmosphere in December 2017 and 2018. Measurements were carried out with the help of mobile ozonemeter (observation frequency 110836.04 MHz), which was established at Polar Geophysical Institute in Apatity (67N, 33E). The parameters of the device allow to measure a spectrum of the ozone emission line for time about 15 min a precision of 2%.On the measured spectra were appreciated of ozone vertical profiles in the layer of 22 60 km which were compared to satellite data MLS/Aura and with the data of ozonesonde at station Sodankyla(67N, 27E). The microwave data on the behavior of mesospheric ozone (altitude 60 km) indicate the presence of both photochemical and dynamic components in its changes.
